So I’m slightly confused with my feelings so hoping you guys can help. So as to not drip feed- ex and I was together for nearly 10 years and had two kids, with a miscarriage before them.
Ex is a fair bit older and we obviously both lived lives before we got together, which was and always will be fine. After 18 months of being together he was still getting messages from his ex-fling(not really sure what to call her) he always told me and showed me as we didn’t have secrets, she was married, was at the time they had been ‘together’ too. We had had a miscarriage and i was pregnant again, when a message came through to him, from her, literally saying “f**k me”. My hormones were all over the place and I went mental at her. She calmed it down for a while but still tried every now and again.
We’ve been split up over a year now, get along really well as we work together for the children, he supports me with my family and vice versa.
It came to light about 6 months ago that he was ‘seeing’ her again, she’s still married to the same man etc. We had a good chat, I told him he was definitely worth more than being with her etc and he promised that she would never have anything to do with our children. But she keeps commenting on his posts on Facebook, which include our kids and it’s sending me over the edge. His comment yesterday was that he can’t stop her, I explained how he can hide the posts which include our children from her, but he’s technologically inept and doubt he will do it going forwards. I know I can’t control who he’s with and I wouldn’t want to, even though I know he can do better than being a bit on the side for her as he’s a brilliant guy and dad, I just don’t want her seeing anything of our children, even on social media. AIBU?
