i have this really jealous boyfriend and how to i make him stop blaming me for cheatn on him?

Well it depends. Have you cheated on him before? If not then you should check out how you act around him and how you act around other people. I've been with the same guy for 3 years now and I had that problem before soo I know how annoying it is. But yea, just make him feel like he's the only one for you and try to think about how you present yourself to other guys.

Get rid of him, for real. It will NEVER STOP. Most guys, despite trying to act so secure, are nothing but insecure posers. His jealousy is a result of his insecurity issues, and sadly, most people will never chance. Their quirks are deeply ingrained in themselves.

did you cheat? if not then cheat on him so that the accusations become really and he will learn to stop accusing you of things. teach him a lesson!!!!!!!!!

If he doesn't trust you dump him. Trust is very important in a relationship.
