I posted here in September 2014 because things were awful between me and partner. We have a 2.5 year old DS and an 8 year old DSS 40% of the time, from partner's previous relationship. I almost moved out in October due to real doubts about him being faithful to me and also dreadful silent treatment throughout last 2.5 years. I didn't move out in the end, although advice on here was spot on and much needed. Guess he sweet talked me into staying. I was so concerned about my son being in a broken home and wanted to try and make it work for all our sakes. Having snooped further (bad I know but sometimes the end justifies the means) I have discovered a relationship with a younger colleague who lives in York. We are in Scotland but he travels for work. This has been going on for at least 2 years - since my son was a little baby. I'm shocked and disgusted by him. I haven't yet confronted him as I'm afraid he will throw me out and I need to find somewhere to live first. My family are 60 miles away so not ideal. And money is tight. Over the last few days he had been absolutely vile and bullying to me. And in front of children. It was his 40th yesterday and I bought some nice gifts which he chose not to acknowledge and has barely spoken to me. I'm desperate to get out ( his house) and tell him I know everything. I'm so angry and in shocked about level of his betrayal and he gets off on being a nasty bastard to me! Why do these despicable men behave like this!!! I'm so hurt and bewildered but don't want to lose control of my emotions until I have a plan. I just ended to vent and seek your advice on how to confront him. Broken hearted for my darling son.
