I guess I don't really see the issue.

First off, your views on sex... are... wow. Holy ****. You waited a year? You are going to have a hard time finding a guy that is willing to play that game.

Second, everybody should love their mother.

Some questions:
Do you live with them?
If so, have you talked about her moving out?

The reason I ask, is because you should have a conversation about how you know it's healthy to love your mother, but the natural stage of life is that you settle down and live with somebody else. If you do not already live with him, ask him if he would move in with you.

If you truly love him, you'll make it work. Life isn't worth living unless you give love every opportunity you can. If you do not love him, than take the cowards way out. Up to you really.

Edit:
I noticed that you already left him, and said something about maybe God will one day reunite you or some such bs. If there truly is a God, it is not going to be one to make decisions for you!!! You can't just expect God to put things on your lap that you don't allow.
