Partner and I got together 2016 he had it in his head I was going to get back with my ex who I have kids with apparently my ex sent a message saying have you told him yet

I don’t get it as nothing happened

Anyway I found out I was pregnant

Fast forward someone told me he cheated with someone from work he swore on our sons lives he didn’t then finally admitted it

Now he’s constantly crying and apologising and remorseful saying he’s lost me for god and it was only back then because he wanted revenge and felt low and lonely

I’m so hurt I don’t know what to do
