So long post, pretty much as the title suggests, when i was 8 months pregnant my sister was happily swiping through her tinder and low and behold my bf face popped up, she screen shotted his profile and sent it to me. When i confronted him he lied at first saying it was an old account but it had shown he had been active that day! He relented and admitted to having the profile but claimed he never messaged anyone on it etc and it was a mistake wont happen again blabla...since then i also found out he lied about having had a sexual relationship with his good female friend before we met. He had previously claimed nothing ever happened between them but must have forgotten what he'd said the next time it was brought up! Its 2 month on and i still havent forgiven him and really dont know where to go from here...any advice??
