Stay or go

My bf and I had this huge fight, after I helped him financially he throws it in my face like I didn't do as much as I did, he tried to belittle and say he knows a girl with more money than me and went crazy talking about my kids dad and calling him names (he never met him) and I don't know if I should stay or go. We've known each other for 10 years (b4 my kids) and have always had a great friendship... Please help ❤️
