I've been with my partner two years and I am going through a divorce. I have a son who is 11. My partner gets at least one text every few weeks from his ex who is also married to another. Usually these are requests to do diy in her shop. However in May they also had a secret lunch together. This quite upset me when I eventually found out and I asked him not to lie to me again. She then sent Face book memories to him but didn't put it on her wall. So the next month August she wants another Diy job done and I asked him to keep his distance this time and say he's too busy. He tried this but she wouldn't give up..BTW we live in a large seaside city where there are multiple handymen available. .and pressured him to do this ..texting all through our holiday. I asked him not to but I've since found out he did the job and lied about it. AIBU to be upset and annoyed with both of them for this? It feels wrong.
