i need advice ):

I just broke up with my 2 year relationship with my ex bf . He kept talking to other girls as friends but I don’t accept it bc before he would talk to a girl and they would flirt , basically cheating on me till I found out . we broke up bc we argued a lot but after 2 weeks we got back together and he was telling me how he really loves me and will change for me but he hasn’t he keeps talking to girls without me knowing till I check his phone . He was also talking to his girl friend about another girl like wtf you don’t do that . And he would ft his girl friends on ft and I don’t approve of that because he was with me . He broke my trust . Now we are not together but it sucks that he never cared ab my feelings . Idk what to do I need advice .
