Ex-boyfriend

So me and my ex boyfriend broke up about a month ago so it hasn’t been too we were together for almost a year and I was deeply in love with him it seemed picture perfect we met through some friends of mine and we didn’t start dating right away he was actually dating a friend of mine so I denied all feeling for him until one day we started texting and we found we had a connection so we talked for a bit then on September 24th he asked me out I couldn’t have been happier jump to now many many fights later we broke up I feel I’ve been torn in two and he doesn’t even care he’s already dating someone else and it hurts like hell still doesn’t help I still have friends about this man i still love this man I’ve tried to move on but when I did I would call them by his name and it all hurts but idk what to do please help me out guys Idk what to do anymore 😭

P.S since someone said it she cheated on him he could even vouch for that and she gave me permission too since she was over him 🤷🏽‍♀️🤷🏽‍♀️
