Love hurts

My boyfriend and I been together for 4 years now...& When my boyfriend and I get into arguments because I feel some kind of way about something or I don’t agree with something and he sees it as me wanting to argue and me being petty, even after I tell him it’s not me being petty to piss you off. Things that are real issues to me will b petty to you but you have to understand that everyone doesn’t think alike..and I get called stupid and dumb and then gets mad when I cry and cry because I get so frustrated and it’s hard. Long story short , he kept talking over me during the argument and kept telling me to stfu so I yelled I’m going to kill myself and hung up and he now is telling me he don’t want to b with me because he is over there shaking and ready to break down to think somebody would wanna kill theyself over a relationship and that he loves and cares about me too much to think about it like that etc etc...and I know I shouldn’t have said it but I just wanted him to shut up for once and listen to understand. I know I gotta just let him go. Like , I need some advice ladies...I need something. I know I can’t force somebody to b with me and I told him it’s fine. It’s going to hurt in the long run but if you want to go I gotta let you go...☹️☹️☹️ im just sitting here real fucked up. I don’t have people to vent to so I love coming to vent you to guys..
