Feeling lost

I'm having one of those negative feelings on our relationship again. Why some guys can claim that they've found the love of their lives and yet, some are always feeling so lost.
I'm attending this Catholic class. On one hand, I do love God. On the other, I feel as though I'm tight down and yet I can't tell he's the right one for me or not.
Why can't I have a decent normal family life on my own?
Why must I wait for something which seems like forever?
Why can't he have a better foresight towards future?
