I cannot tell you what the future will hold. What matters the most is that you entrust the entire situation to God, asking that his will be done. In every healthy and mature love, there must be a level of detachment, whereby we allow God’s will to take precedence over our own. Falling in love is a marvelous and unforgettable experience. However, during this time of intense emotions, it can be very difficult to resist the temptation of making an idol out of a person or a dream we have. Then, if our dream does not come to pass, we find ourselves inconsolable.
I know what this is like, because I’ve had relationships in which I knew I had met my soul-mate. I thought about her without ceasing, and could never imagine finding someone more amazing. However, one of the young women never seemed as interested in me as I was with her. The other one ended up breaking up with me after we dated for a while. In both cases, the situation was very difficult to accept because I had definitively set my heart upon the other person.
But through the pain, God was able to teach me to keep my eyes upon him, and trust that he had a plan in mind for me. If I had harbored the idea that if I can’t have the first girl, then I will never date again, I would have missed out on my wife and family. From time to time, I'll run into her (because she married a friend of mine), and I am glad she is doing well. I'm also grateful that God knew what was best all along. There’s a country western song that says “Some of God’s greatest gifts are unanswered prayers,” and I think there’s a great deal of wisdom in this.
I cannot say if you will or will not end up with this guy. All I can say is that God’s plans for you are wonderful, and he wants you to remain at peace, trusting in him at all times. He’ll take care of the details if you keep your heart at rest in him.
Aside from the spiritual advice, don’t try too hard to make a guy like you. You’re the prize, not the pursuer. Instead of running after him, it would be better for you to give him the space of wondering what his life would be like without you. This isn’t about playing mind games, but about having the confidence to give a person some breathing room when they need it. If he truly loves you, he’ll realize that he doesn’t want to leave.
