“I think if we were in a relationship and we had an argument, you’d crucify me”

Hello mother cougar, I was just wondering why guys are such amazing fuckheads ? Recently my boyfriend of one year dumped me over text and gave no reason. We share many mutual friends and he has told all of them different reasons for dumping me. Not one i would consider legit... It's shit like 'we had a fight' (which we didn't) and 'she was nasty to me' (Bull-fucking-shit he never said jack shit to me about anything). I've moved on and now he is saying even more shit. How can i make him shut up ? How can i make him see i just want to be his friend ? What the fuck is his deal ?
