he's gone crazy

my throat hurts. he called me up today, he used his sister's account to sift through my fb to find shit to be paranoid about. and then he tried to interrupt my night spending time with a family friend to bitch about it.
i called him back later. he kept me for an entire 40 minute car ride. screaming. he drives me up a fucking wall. i can't count how many times in the last 4 months he's asked me if i've been with someone else. NO, i say. i am not going to tell him what he wants to hear. maybe i should? i just want him to go the fuck away at this point. i can't deal with his insecurities. he brought this on himself.
he's also been looking through my internet history, why does he want to confirm his fears so badly?? why can't he just be a man and walk away?? he has to find me in the wrong.
and we had this peaceful ending to a tumultuous conversation where we said "i love you" and i'll talk to you soon...and then he just HAD to call me back and upset me some more. start a fight.
now my fucking throat hurts from yelling. my blood pressure is out of control. he seriously makes me so angry i want to bang my head against the wall. i'm probably lucky i didn't get in a car crash while arguing with him at 70 mph earlier on.
anyway. apparently we're finally trading back keys, etc. when he returns from vacation. finally. sad, but good. jesus christ i can't deal with this shit anymore. it's just getting worse and worse. and the more he tries to push me into a corner and control me, the further from him i want to be!!
