This is a massive vent into the ether because saying it in real life would cause problems. My STBXH is an impulsive selfish dick. He's generally a good dad and I could have a much worse experience as an ex wife, but I'm fed up of being forced into the role of Responsible Parent because he and his fiancée are too impulsive to rein in their excitement and behave like grown ups.
STBXH, it WAS NOT OK to introduce your new girlfriend to our children after knowing her for 5 weeks.
It WAS NOT OK to move your girlfriend into your house that you share with our children every other week after knowing her for 5 months.
It WAS NOT OK to book a wedding before divorce proceedings had begun.
It WAS NOT OK to try and pressure me into agreeing to rush the divorce through because you had a wedding booked.
It WAS NOT OK to tell me I didn't deserve 10k of the 430k you possess because I 'didn't meet your needs' when we were together. Newsflash! My needs weren't met either, it's why we're getting a divorce, dickhead.
And you're supposed to be the neurotypical, responsible, fully abled, reasonable one. Why am I, as an autistic disabled single mother, in the role of damage limitation, soothing our dc through the last minute changes that you and your fiancée force upon them with no warning or preparation on your part. SELFISH. FUCKING. WANKERS.
And breathe....
Mn, Thank you for humouring me. I feel much better. As it turns out the fiancee is really lovely, which is lucky, but my dc still need time to process.
