So I've just found out that last month after my partner and I had a stupid row and he'd said it was over that he shagged someone - it all happened after a massive fall out one night where he had kicked off and I'd locked him out - yes I know not good all round from either of us. Turns out he called some woman I think that he knows from his old OLD days who lives locally and asked her for a lift to his house - given how furious he was with me somehow he said one thing led to another and they ended up shagging in her car. We didn't speak for a week after our row and then he was in touch to confirm he wanted to end it. Anyway we ultimately worked through and we decided to continue our relationship. From this point when we started having sex again we used condoms as he told me he thought he'd picked up thrush which as we all know doesn't have to be through sex. He got tested for STDs and thankfully all clear but has only just told me re the ONS this weekend when we argued about something else. He straight away admitted it had made him realise what he's got with me, said how much he hated himself for doing it and apologised for hurting me. Obviously I was devastated to hear what had happened...AIBU to think we can get past this? I want to but I am of course massively struggling with what he did. He said if I'd only let him have his keys before locking him out he'd have just gone back to his house and it's only because I didn't that he ever made the call for a lift and you know the rest as above...he isn't in contact with her and has as you'd suspect told me it won't happen again...he is snoring away next to me and I'm sat here wide awake and feeling like crap...did make me think of the friends storyline where Ross and Rachel are on a break...what's everyone's thoughts please, can we move forward despite what's happened??? I love him and want to. We've been together 3.5 years BTW and he's a massive part of my life...
