ExH and I have been split for nearly 3 years. I have been in new relationship for 2.5 years. ExH and I have a 4 year old DD.
ExH is crap when it comes to turning up for visits / phoning his DD etc, is very argumentative all the time and is basically a nightmare to deal with.
He has a new GF of about 3 months, she is 7 years younger than me and has a DD of 3. She seems pleasant but keeps butting in and telling me I'm wrong to be angry at ExH for not phoning / not turning up etc, and that she wishes I would "think of my child". TBH it hacks me off that this young girl is telling me how to parent, as far as I'm concerned I'm a very good mum and try to be the best I can possibly be.
But... she sent me an email was was lecturing me again (and going on about how wonderful my ExH is with her DD, hit a raw nerve as he's so crap with his real DD) so... I told her that my ExH said her DD 'was a bit thick'. Which he did. I still have the text.
But now I feel really mean
