So I’ve been in a relationship for a year and we just had a baby in august his first and my second he recently asked me to marry him on my birthday in September. But I’ve just recently found out from some mutual people we know that two days after we started dating a year ago he was hanging out at another girls house and kissing her. And I’ve asked him before if he had done anything with said person after we made things official and he told me no. I’ve never lied to him about anything from my past and anything he asks I always give him honest answers especially since he knows I was struggling with a lot of issues after my first child was born being a single mom and working a lot and having some substance issues. I’m just not even sure how to bring it up to him or if I even should. I’m just baffled that he wouldn’t be honest and kept it from me for a year.
