Again if your boyfriend, if that what he really was, engages in excessive contacts wuth your female friends then the issue is him, not those female friends who might not even know he is your serious boyfriend. You keep blaming her but you never blame him. Why?

I’d look deeper into reasons why you can’t discyss with a man you are dating? Is it that he wasn’t really official serious boyfriend but more just the guy you liked? Or is it that you are afraid to address issues with men yiu date?
