Another Valentine's Day when it appears that everyone in the world has a perfectly happy committed relationship. In other words, a day when most of us writhe in disappointment.

It's not that we're saying we're not loved at all, or that we don't love, or that we've never tasted love. The frustration I hear most (in my office, in the media, and from friends) is that, "No one loves me the way I need to be loved." And sure enough, as spring blooms, scads of those happy couples around us will break up or divorce for just this reason – at least one person didn't feel adequately adored.

But ask if they've ever felt loved in the right way–even by an animal–and you're bound to hear,  "Oh! Well sure. My dog loves me unconditionally, but no person can do that."

Really? Ask a four-year-old how they feel about their mother. You won't hear a lot of conditions. Or, more relevantly, ask a new parent how they feel about their teething six-month-old baby at 3:15 a.m. Would they actually make a trade for freedom and give up their bundle of joy? "No way!"

Why not? Because their love is unconditional.

So why are we so damnably bad at giving such love to each other?

From what I've seen in my practice, it's because of a lethal mixture of two curses: Scoreboards and Entitlements.

From the time we turned about five years old, we started caring enormously about whether any peer relationship we're in is "fair." This extends from how long we're allowed the ball on the playground, to deep hurt about grades on seventh-grade homework, to an enormously complex Scoreboard in romantic relationships. "Did he respond to my text within three minutes?" equates to "Did she clean up after dinner last night?" equates to "Am I the only one who wants to become a parent?" equates to "Does this person love me?". . . And all equate to the timeless query, "Will you still love me tomorrow?" (Note, I emphasize that this only applies to same-age relationships. When that infant is screaming in our arms, we accept that our relationship with said baby will be a one-sided deal for at least a while – or that a cheerful smile or hug is payment enough.)

This Scoreboard mindset would be bad enough, but then throw in Entitlement, and things get far worse.

Imagine a couple, with a woman who always returns texts immediately but is a bit messy at home, and a man who's a neatnik in the house, but sees no reason to respond to a question until he has some convenient time for it.

Now, she doesn't see her promptness as anything special, while he feels the same way about dishwashing. Therefore, both feel egregiously insulted when the other doesn't naturally do the same as they would. They consider their behavior "normal," and believe that anyone in any relationship should be entitled to their partner behaving this way.

The best that can happen in this situation is compromise. This occurs when each partner communicates well enough to come to an agreement, such as, a clean kitchen "equals" swift texting response time. And this certainly makes for a calmer home. But in a compromise, neither participant feels that they're being loved unconditionally. Peace, but no rapture.

If only each could learn to love so unconditionally that both believed it all the time, imagine how happy and secure the relationship would feel.

Is that possible? Of course it is. We just need to consult with an expert on unconditional love. Someone who understands it so deeply that they can't imagine living any other way.

In other words, let's look at what we can learn from dogs.

When you feed a dog, it's thrilled. When you pull out a leash, your pup will dance to put Gene Kelly to shame. When you come home after a long day away, your dog will celebrate the Second Coming.

Yet we hardly ever give our partner the same honor. If your lover brings you flowers, or a case of the flu, do you regard it as a gift, just because it's from them? When they make mistakes, do you thank them for having tried? Do you thank them for going to work and making a living? Do you thank them for grocery shopping, for taking care of the kids, for just being yours? Do you thank them for eating well, taking vitamins, buttoning up their overcoat, because they're then taking care of the thing you value most?

Love is an active word. Dogs do "love" all the time, while we do a lot more analysis, scoring, judgment, resentment, and taking-for-granted. Whichever you do, you're likely to get the same in return.

The core of "unconditional" is to be free of judging. We don't look at a dog chasing its tail as doing something wrong, and a dog doesn't look at us spending hours staring at a glowing box as stupid.

If Jane loves to shop while Jim loves baseball statistics…so WHAT? Why complain? Enjoy their quirks, habits, obsessions for what they are! Or, as the old Sinatra tune crooned, "I've got some habits even I can't explain…why try to change me now?"

The Golden Rule says to do unto others as you would have them do unto you. Any mutt would hear it and scoff, "Amateurs! That rule still has a scoreboard!" How about treating others better than you would ever treat yourself?

A dog devotes herself to protecting her family, giving constant love, entertaining them, and mostly offering consistent obedience. How about using that as a role model, instead of the latest online dating sarcasm.

The greatest advantage dogs have over humans is their lack of shame. Their smaller brains lack self-consciousness, so Fido rarely judges himself the way you do.

So how does that affect their ability to unconditionally love? It makes loving so much easier.

If your beloved says he is too busy to talk to you right now, see that as their issue; maybe they're working too hard, or are too stressed. And maybe you can do something to help them through that. If you curl up on your partner's lap and they push you off, just know that they can't deal with you right now, and try again later. Maybe they're in a terrible mood, maybe they're ill, maybe they're in pain. Whatever it is, your instinct to make it about yourself will only make things worse!

Feel free to be annoyed at your beloved's behavior (any mutt would), but always fight against any voices inside you telling you why they did it–especially if that voice says it's because of something wrong with you.

Unconditional love means that you love fully and with an open heart. When someone takes advantage of that, or simply treats you too horribly, you don't need to stay. Even if you still love them unconditionally. Love doesn't equal taking abuse. And you need to treat yourself with unconditional love (as dogs do) before you can truly give it to someone else.

Love isn't easy. At least not for us homo sapiens. Our self-conscious, over-sized brains make it an endless trial. But if you just follow these suggestions, you can get what is promised in the old song: "The greatest thing you'll ever learn, is just to love, and be loved in return."

And, if you need further Valentine's coaching, your local animal shelter should have some great professors. They're just begging to help you all they can.
