So not that long ago I started talking to my ex boyfriends friend which is my friend too , keep in mind my ex-boyfriend was the one who wanted to break up around July , he wanted to break up for a really long time and after we did he wanted me back I but didn't want him back and I've moved on I don't care or like him .  But I want to know if I'm wrong for talking to his friend ?.. It's not like I planned or did it on purpose it's just we started talking and we hang out but also my ex-boyfriend always gets mad about it . ( my ex still calls me cute & today he pretty much tweeted saying "missin you." , & he's talking about me . But he is also talking this girl sooo) any advice ladies ?🤔🙄
