Drop her.
Get out. Get out now.
You’re making her miserable and yourself miserable.
IF, say, you marry, you’ll have a miserable marriage, you’ll want out and SHE won’t let you get a divorce!
You say that you don’t want to convert. If you did, you’d make a miserable Catholic and, as she’s so gung-ho, you’d have a hard time of it–VERY hard time with some things, like birth control, unless you get a vasectomy after, say, 2 children, and don’t tell her. Not a good idea.
It’s up to HER to find an observant Catholic, not to try to make one out of you.
Get out NOW.
