So I was in tesco with my ds (4 next week) and my ex's brothers partner was in there at the same time (I don't know if I should call her my ex's SIL as there not married?) anyways she's 8 months pregnant and tbh I never got on with her. Actually I don't know if thats right because we've never actually spoken. I was with my Ex for over 5 years and she has been with his brother just over a year now. Anytime we were in the same company she would completely ignore me even if I said hello which I just gave up doing in the end. Everyone used to tell me she was just shy but in the end I stopped listening to excuses and realized she wasn't shy just extremely ignorant.
When in Tesco I didn't actually realize that she was there until my ds said 'Thats so and so' I replied with a 'oh is it' and we carried on with our shopping nothing more to it. That evening while talking to my ex over the phone he comments that so and so had seen us in tesco and that my ds had shouted her name excitedly and went to run over to her when I grabbed his arm, yanked him back and said 'Stay away from her, where going this way!' and dragged him away in a state.
I'm at a total loss at what to do. I know I should ignore it but I feel quite angry at the fact she has gone and told my ds's grandparents, uncles and aunts that I treated my son this way. I feel she has made me out to be a bad mother and a petty person. I just don't understand! So WWYD?
