I have a whole thread on the issues surrounding me and XDP but I am absolutely livid and might possibly need a grip handed to/some sense talked into me. Thread here if you want to read. Long story short he behaved disgustingly then had an affair with someone at the company we both work for when I was pregnant/had just given birth. I don't have the exact date it started.
Today he called my DD (7 months) something unusual and I asked him to repeat himself thinking I had misheard. It's fucking ridiculous and not something I would ever call a child
Turns out the OW, (who knows she was the OW) has decided it is cute and it is going to be my DDs new nickname. Has apparently told people at work this is DDs nickname and several have started using it. XDP had started using the name reinforcing this until I have absolutely flipped. She has previously posted on FB about meeting her "new daughter" aswell which I have put a stop to and he is not taking DD to meet this woman. I haven't allowed him to have DD on his own since I found him trying to take her to meet the bitch.
AIBU to not want her giving my DD stupid nicknames?
WIBU to message her and tell her the "new daughter" comments and stupid nicknames need to stop, and that she has overstepped the boundaries by miles and needs to fucking back away from my daughter?
