anxiousness and relationships

I think there is an anxiousness in starting relationships that comes from fear of rejection, which seems to be only natural. However, I wonder if a person were to totally put the relationship in God's hands, that they could relax and let it go, because they knew God had it taken care of. If God wanted it to work out, it would, and if not, it wouldn't. All they had to be the person God wanted them to be towards the other person. Does the anxiousness come from trying to control somebody else's response? I wonder if this ties in with Cloud/Townsend talking about how if a person tries to control someone else they become out of control themselves.

I wasn't trying to say everything is God. People do have to make themselves available. Boundaries in Dating by Cloud/Townsend talks about this. But ultimately a person should be able to walk in peace rather than feel tremendous pressure. I think this is more than theory...
