I picked up my husbands phone last night and saw he had text messages from his ex. I opened them and I know I shouldn't have - basically telling her if he 'had his time again' and how great she is looking.
I'm 7 months pregnant with our first child. I'm beyond devastated. I don't know what to do 
He's apologised, says it's stupid, was an outlet - we've been under a lot of stress with things going on. The messages weren't innocent and very flirty but I just feel so betrayed.
He said he really messed her up and was trying to make her feel better - she even referenced that he was married and she said but she would be interested in going back there if he was single. I don't think he would have met her or anything would have happened but I don't know what to do. I obviously confronted him... he is now devastated and I'm threatening divorce.
