Am I wrong for wanting the same?
No.
God's love is more than enough to sustain me, but why do I long for human compassion?
Because that is how God made you.
Do not let anyone tell you that there's something wrong for you because you desire a good relationship with another person. God made people to desire fellowship with one another, and he gives us the commandment to love one another as the second greatest commandment. Some people think that that only requires good works pursuant to a detached, intellectual acknowlegement of another person's needs, but I do not believe (nor has anyone been able to prove to me by scripture or reason) that you can properly love another person unless you also have an emotional connection to them. We register caring and empathy in the form of emotion. It's not always rational, and it's often rather messy; but it's what we have to work with.
The desire to love another in a romatic sense is only the natural outgrowth of the above. We should care for everyone. On that, we practice agape - love by choice. Some of those for whom we care will share deeper connections with us. That is phileo - friendship. Eros, or romance, is phileo with a narrowed focus, and therefore, greater intimacy.
Agape for all, phileo for some, eros for one. That is the way God designed most of us. Those whom God did not intend to experience eros were not created with it. And those who preach that there is something wrong with a person for acting according to his or her design, I believe, cause their brothers and sisters to stumble. We love God first, but not solely. Without love for God we are incapable of loving other people, but as scripture says, the one who says he loves God and does not love other people is a liar.
I know that I should seek first the Kingdom of God, but I also know that God will fulfill his promises for our lives.
I agree. God does not create a desire in a person without intending that that desire be fulfilled. God created eros, just like he created agape and phileo. If you desire it, then you should seek it. So long as you are doing so in pursuit of God's Kingdom (which is based on love for one another to begin with!) then you have no reason to worry that you are straying from your purpose.
As for why it has not yet been fulfilled, I cannot answer that. I sometimes wonder if my own desire for a relationship has not been fulfilled because of something I've done wrong, but I would never suggest that as the reason for someone else in a similar situation. I'm in no position to make such a judgment. But I can tell you that I understand, as I am there myself. I think you're on the right track in learning to be otherwise content in your life. If you find yourself unable to shake the sadness of it, my practical advice would be to find something new to learn or do. Many great minds achieved their greatness out of a necessity born of solitude.
