I hope I'm on the right thread for this, and I'll keep it as short as possible but I really need some advice.
Have been divorced for over 10 years and DD is at University a few hours drive from home. My sister and I haven't always got on; she is slightly younger than me, never married no kids. She can be slightly narcissistic at times but I am used to that now. When I got divorced, she was on-side, completely supported me, called the Ex a tosser, amongst other things etc, and was loyal. None of my family kept in touch with him, to my knowledge.
Fast forward to now. We haven't spoken much for about a year, she has gone low contact with me and tbh I haven't wanted confrontation because this happens every so often, and she eventually comes back and I am happy to pick up where we left off. It's not a "something I have done" scenario, she just gets tied up in her own life and job and goes a bit off grid.
Last night I spoke to DD who told me that last weekend her DF and SM went to visit her at university, took her out for dinner, and that my DS went with them! I am horrified/upset/shocked etc.....I managed to keep it together though, and said "how lovely" and other platitudes but as soon as I put the phone down I burst into tears which is very unlike me but I was so shocked that she could be so disloyal, or more accurately duplicitous. So all the "he's a tosser, blah blah" was either just to shut me up ten years ago, or she has no sense of loyalty. To be clear, when exH left, he paid very little/nothing in CM, and is a true Disney Dad, even now. He buys all the fun stuff, and I get to finance everything else. Having said that he never took her on holidays, that was apparently my job to do (and pay for). I kept a (relatively amicable for the sake of DD) civil relationship going but we never saw one another.
So now, what next? How do I approach this with her? OR do I just ignore it ever happened and say nothing? It's just so hard thinking that this is all going on without my knowledge - but I also feel that I need to continue to keep the peace, and the pretence, for the sake of DD.
I would love to know if anyone on MN has had a similar experience, and might have some pearls of wisdom - to protect my sanity!
Thank you so much in advance.
