I'm going crazy and sometimes I have good days but every week or so, I just have complete melt downs over stupid things which blow up into bigger arguments and then my boyfriend just leaves. I know he sometimes needs to cool off a bit after an argument, I know that. I really do know that.  But I can't stop blowing up his phone,  calling it,  texting it nonstop because I'm so paranoid that every possible thing could've  happened while he's away from me. 

I stupidly convince myself that he's off with some girl with absolutely no evidence at all, other than the fact that he's cheated once, but it happened a long time ago and I know I'm over it but after a fight,  every single alarm bell just starts ringing. 

Usually,  when we don't fight, I have no problems with him leaving or doing things by himself. But when we do, it's like complete overload and I really can't control or stop myself from overwhelming him with messages and calls. It's gotten to the point where we've  both gotten so sick and tired of it. Like,  I can feel and see myself doing it and being annoying but I have zero healthy way of stopping it. 

Please help,  any advice would be appreciated. I'm so scared of him leaving and never coming back, even though he does every time,  but what if this time is different? Even though I've thought that every time

Arrghhhhh  any advice would be really helpful, I'm really at wits end.  thanks guys
