My partner started working with me as I was going on maternity leave,a new girl started but I thought nothing of it,soon after a lot of romours started to go around work about them and put a lot of strain on our relationship,they are good friends and text each other a lot,2 months after I had my baby girl he started acting weird,was very nasty to me.he even put a password on his phone. a month later he split up with me and my world fell apart! I said he could stay here until he found a new place,I knew something was going on so when he didn't expect it I stole his phone,which had a pass word on it.I said I wanted to look at music so he took the password off,I then looked through his phone and found very explicit messages from her and from him.we are back together now and he swears nothing happened apart from a peck on the lips,but I can't trust him,I keep having panic attacks and can't stop thinking about it,it makes me feel sick,I know we wasn't together when the messages happened but it will tear us apart and I don't want that! Please help!
