Troubledgirl,
I can understand your concerns, seeing as I still sometimes worry that God will send me someone I don't like (and I'm 40.) This is because I've met Christian couples who felt God was telling them to marry their spouse and it WAS someone they were totally uninterested in at the time. (From what I've read, Martin Luther of the Lutheran church had no interest in marrying his future wife, but she was reportedly very persistent.)
I used to think I had a "type" as well but have found it's really died down over the years. As I've met and been exposed to different kinds of people, I've discovered that there might be something about someone I'd never considered before that I could really fall for. I am Asian but did not grow up around Asians--I always pictured myself marrying someone white because that's all I really knew.
The guy I wound up marrying was half-Asian and half-white. I would have NEVER in my life thought I'd marry an Asian because I'd heard so many horror stories of Asian families completely rejecting someone adopted like myself. But I was crazy about him. There were things about him and his experiences that no one else I'd ever met had ever related to in my life (such as, being called an Asian racist name and told to "Go home" or having kids "slant" their eyes at me in public, which I still sometimes get even as an adult.) All of these unique experiences created a deep bond I had never known could exist.
Sadly, things did not work out but it was an important lesson. I fell more in love than I ever thought possible with someone who was very different from what I had envisioned. This will sound trivial but several years later, I went shopping for a certain kind of car and I had a very particular color in mind. The dealership didn't have the color I wanted but gave me a deal on another color they had in stock. I grew to love that car even more than the one I originally set out to buy.
I honestly believe God was saying to me, "What if that's how other things will be in your life, Kim? What if I put things or people in your life that you never thought you'd accept, but I know you're going to love them even more than you could have ever thought? Will you trust me to do that?" God knows us better than we know ourselves, which I know can be frightening and hard to admit. One of my best friends always tells me, "God may not give you what you want, but He will give you what you need."
I really do understand your fears, Troubledgirl. Would you believe I still have them too? But I know God has worked with me over the years and I'm not as afraid anymore (though admittedly I do still have a little bit of fear...)
But I know He is faithful and will continue to work with me... and as you pray to Him, He'll work with you too.
Blessings to you!
