Would god actually prevent a bad relationship from starting.

I have been single my whole life and when I open up about to people. Most of the time they say something akin to “ God has the right woman out there for you” other times when I showed interest and got rejected people will say” God just doesn’t want you with that person because it’s a bad match” personally I just don’t think the girl ever liked me. But I see other people get in relationships and even marriages that end up in broken hearts and divorce. Why would God stop me from getting into a relationship just keep my heart or someone else’s heart protected but not others? I would rather believe that I’m just not attractive than the idea that God is stopping me from going into a relationship.
