I'm glad to hear that things are otherwise looking up for you, after such a hard breakup. Even if you haven't been together much, it's still an emotional wrench to separate two lives.
It's very wise to not look for someone else yet. You need months, perhaps even a year, to grieve something lost; you certainly don't want to take anyone on the rebound, when you're dealing with too many diverse emotions. You can spend the time concentrating on college classes, volunteering, working on art and writing, and making friends.
I've never been married, and not even in a real "committed relationship", or anything of that sort; but there was one guy a few years ago who'd expressed a bit of interest in me, and I fell for him--hard. I don't really think I've gotten over it yet. I've got lots of guy friends, but no one I've ever felt the same about. And yet it's been great for my writing and music. There are parts within our souls, I think, that never quite develop fully without love and loss. I don't think I'd have made it through some of the great loneliness without my faith in God, though.
I'm so glad to hear that you're giving church a chance again, and I hope you find one whose people don't let you down. I'm praying! :)
