Hello there, I'm new to this site and a bit overwhelmed so forgive any etiquette blunders. I'm desperately seeking advice on my rights and any channels of support when it comes to my ex husband and his girlfriend(s).
I separated from my husband 18 months ago when I found he had been arranging to have sex with women online. We have been divorced a year. My 4yo daughter lives with me. My husband sees her on a Wed after school and Sat daytime only, no overnight stays. In the time we've been separated, he has introduced my daughter to 3 of "daddy's friends" (that I know of) and is now living with the latest having met her online less than 6 months ago. My husband's online dating profile that ensnared this woman showed him and my daughter in a photo juxtaposed with a vulgar offer of "amazing sex" in his bio. Further context that seems relevant is that during couples therapy he was diagnosed as a sex addict for which he has not sought help. He is a narcissistic, misogynistic master manipulator and, through the divorce, has colluded with my mum and destroyed my relationship with my family - an example being that he had my mum encourage me to agree that we should remain married whilst he sleeps with other women. This 18 months spent alone has given me the space to reflect on the way he treated me, particularly with regards to sex and I'm beginning to realise that a lot of it was not OK.
What leads me to this email is that, having met his most recent girlfriend online in Sept, he moved in with her in Dec. He didn't tell me he was moving in with a partner. He has gone to lengths to conceal her name from me (I had to ask for proof of a negative CV19 test and he pixelated her surname and DOB). He parks a road away from the house when she is in the car so I can't see her when he drops my daughter off.
Now I hear from my daughter that the girlfriend baths her during the daytime when she visits. The girlfriend uses the toilet in front of my daughter whilst they are at home. My daughter tells me she has "seen" this woman's private parts. The pair of them are now telling my daughter that she will be staying for a sleepover soon and this woman is going to sleep in a single bed with her.
Whilst individually, these events may all seem innocuous, the sum and the context is making me feel sick. Whilst I hope it's unlikely, it's not impossible that this woman has dark motives. She may just be young and naive, but if the pair of them aren't able to see that this is inappropriate I don't know where they have drawn a line. I don't want my daughter to stay over with them but I don't think I can insist she is brought home. Everything I've read on here suggests that whilst my daughter is in his care he can spend time with any adult he wants. None of this is sitting right with me and I really don't know where to turn. Any advice would be much appreciated.
