Cheating.

4 years ago my husband was in a warehouse retail job

(had been for a while) he walked out of work and quit his job and his story was he had been caught cuddling a female and he wasn’t social distancing so his boss caught them and threatened to fire him so he walked out. Fast forward I never believed the story I always knew there was a little more to it. I always knew they were atleast caught having a kiss. I don’t know but it diddnt make sense. I always pulled him up on it so many times. Over the years I felt stupidly paranoid and insecure. I always thought it was obviously in my head because that’s how he made me feel. He is such a flirty person with so many women he is like it with and it upsets me so bad. Fast forward yesterday after a deeply long conversation and days of me asking because it really got to me now and I had spoke with someone from his old work who had told me there was something going on. My husband told me. He said it was constant flirting and kissing for 3/4 weeks. He said it was an escape because I suffered very badly with post natal depression and I was in a very bad place at the time. We hadn’t even been married a year. He basically used me as a reason. But rather than entertain someone else at the hardest time he wasn’t there. I feel broken and hurt. I have made him leave and go to his dads for the night atleast so that I can think and have some breathing space. But my question is could you forgive him? He says there was no feelings on either side but I don’t believe that for a minute. You can’t spend weeks kissing someone and there be nothing in it? I’m not stupid. Could you move past it and make your marriage work?
