Hello. I don't know if you exactly came to this board to get the advice to simply break up with him. So I don't know if simply 'break up' is great advice. The other posters are probably right. It could get worse. The controlling behavior is definitely not making you happy. You are probably better off single. But at the same time you care about him. And you probably enjoy his company (for the most part).
I think the question you have to ask yourself is: if you confronted him with his problem, do you think he could actually get better? Do you think he'd change? You can't change him. That is for sure. He has to do it himself.
You sound like a girl of faith. To me, whenever I have a problem with a relationship, I am sure to present it to the Lord first. Sometimes these situations seem hopeless. You probably don't know whether to leave (and it sounds like you are a catch and would have no trouble finding someone else) or to stay (after all, you probably do value his companionship). I would say do what feels right in your heart. To say 'break up' is pretty narrow minded. Afterall, you could have posted this right after a bad episode and have exaggerated his behavior, who knows? I have definitely posted things and then afterwards I realized the problem wasn't as big as I thought. Give it time and make a decision when you are level headed but above all else, make sure you are safe. Good luck to you.
