my bestfriend...., I need help!!! Options

[alcohol_bandages]

Alright, my bestest friend in the whole wide world... is my ex boyfriend. We met last year and went out for about 7 months, then I broke up with him for the most stupid reason in the world. Now, I pretty much think he thinks I'm one of the guys or something. Because he talks about sooo much gross stuff!! In the beginning I really didn't mind it, but now it's freaking annoying and racks on my last nerves each time.

Which brings me to my next problem...

I have a short fuse and I pretty much everytime that happens or something wrong is said, I take it way too seriously. I've been trying for months to overcome it, but I let it build up and then an outburst of rage follows. Take today for example, his bestfriend is a total jerk to me. he always had been! and recently I've started to say things to his face instead of talking to my best friend (his best friend too) about it. Now my best friend is taking shots at me saying how maybe if I was nicer, he'd be nicer! I've tried that, TRUST ME it didn't work at all. It's like that jerk has brainwashed everyone into thinking I'm the cause of everyone's anger and it makes me feel like even the freaking war in iraq is my fault too. I'm all out of things to do!!! I don't know what to do, or say without possibally loosing my best friend. If I loose him, my life would be over.

any advice on what I should possibally try doing?
