The fact that he called you a cunt isn't as scary to me as his reaction to being called controlling... he IS controlling, and the fact that being called out on it caused him to lose his temper is scary.

I'd put money on this not being the first time that he's been pissed about you being around other men. In normal realtionships, both people have friends they go see and things they go do. They don't have to check-in constantly, and they don't have to justify why they talked to each individual person they ran into in their time out.

You shouldn't break up with your boyfriend just because he called you a cunt, but it is one of the reasons that this particular internet stranger thinks that this relationship is badnews. You should break up with him because he's controlling, and yells at you when you try to talk to him about it. You should break up with him because calling you a cunt for being around some unknown male is only the beginning.

It's so easy to rationalize away this kind of treatment, and I'm sure when he shows up again he'll be all romance and tenderness, telling you its just because he loves you so much/is so scared of losing you that he gets too emotional or whatever. He'll say that if you would just do what he wanted, he wouldn't have to get like that. Make no mistake about it, even if he apologizes he'll find a way to put this on you and make it your fault... he'll say that he reacted poorly, insinuating that your behavior needed a reaction of somekind.

There's nothing wrong with going out with your friends, and even if every single one of them brought their boyfriend, and even if the bar was FULL of 'guys he doesn't like' there would still be nothing wrong with it. His behavior was totally over the top. If you let him call you a cunt this time, he'll keep doing it until you're used to it... and then he'll start grabbing you or pushing you roughly, until you're used to that too. Don't get used to being mistreated, someone who loves you wont isolate you from your friends or call you names. You're right, this guy is controlling, and the fact that you've been with him so long seems to make him think that he's earned that control.

I hope you get out before it gets worse... I didn't. I'm speaking from experience when I tell you it only gets worse from here.

Good luck. Take care. Don't let him tell you this was all a big misunderstanding... there's no way to misunderstand him calling you a filthy cunt.
