... to my daughter's partner again?
They've been together 5 years with a nearly 2 yo dd.
Over a year ago dd found he had an addiction to porn and was contacting prostitutes (although according to him had never been with any). She came home for 5 months but with counselling and many promises to change she forgave him and went back. For dd's sake I managed to stay friendly and tried to get over what happened although I found it difficult.
Fast forward to earlier this week and dd found out he was contacting a girl from his past and had been in contact sporadically since approx 2006 although dd didn't know. During this time the more recent emails became sexual and she recently sent him her phone number and they were going to meet up. In his emails he told girl he didn't love dd and baby (who was planned) was a shock.
Dd was going to come home but when she challenged him yesterday he asked for 6 weeks to change and now dd is staying and she could well stay for a long time.
Not sure of any relevance of following but don't want to drip feed.
She hasn't been happy for a long time and they don't talk about their problems. He can only manage intimacy once every 2 months. He has his own business and is a hard working man but is very mean. His home is owned by his parents so they pay minimal rent. He helps me with DIY etc as I live alone. Dd works 2 days a week and hasn't got much money. I provide child care 1 day a week while she's at work (child minder second day) and quite a few half days if dd wants to go anywhere. Other grandparents live away and dd and partner have no close friends. He has a 15 yo ds from previous relationship. They are both mid 30s. Dd has made an appointment at Citizens Advice for Monday and she is keeping the appointment.
So AIBU to not want anything else to do with him? I don't want to lose dd or dgd through this but I don't think I can play happy families any more. Or should I forget how I feel and be friendly just to please dd (I'm not sure if I can). Is it any of my business at all (although the outcome if she comes home will be my business and I feel seeing her so downtrodden is my business too (or am I an overprotective mum?) I'm very confused. Wwyd?
