But he knows it’s not working
If you're going to break up, then just breakup. Throwing threats and going back on them is some weak wishy washy shit.
He literally says he’ll kill any other guy i mess with
He says “whoever else you date is going to die”
The man is in love, and now that he's losing you, he can't grasp his emotions in a rational way. He's lost it. It's an extreme sense of abandonment and betrayal he's experiencing. Most women monkey branch into other relationships when they leave a guy, so he's most likely assuming there's another man who has gauged your interested and simply becoming defensive. You're only hurting him more by stringing him along if you genuinely want to leave.
I'm not rationalizing what he said either. He's clearly in a manic state and unstable.
Or he’ll say “im going to fight and beat their ass”
