AITA for refusing to let my son’s family come to Christmas dinner after what they did to me?

I am a 62 year old woman, married for 4 years to Chris who is 67. Chris has a daughter we will call Laura who is 28. Laura is married to Rob, 32, and has two kids aged 4 and 6. We get along fine though I don’t feel close to them. Laura spends a fair amount of time with her mom. I don’t have any kids of my own. I was married before and am divorced. My son is the result of an affair between my then husband and his best friend’s wife. I was aware of the affair and had agreed to the marriage being open. However, naturally I wasn’t aware of the specifics of who was involved. Laura’s mom was not.<br><br>My son, Nick, is 29 but he is disabled. He has severe CP and needs pretty much everything done for him. I raised him on my own for 19 years, and then he moved into a group home when he was 18. The process of getting him in there was a nightmare, and getting him the services he needs still is. But he lives a happy life. Chris knows a little bit about Nick from talking to my friend, but he doesn’t often ask about it. I’m not trying to hide Nick’s existence, it’s just that Nick’s life is very complicated and Chris isn’t really interested in learning about it. Laura has never asked about Nick. Her mom knows a little bit, but she does know about the inheritance.<br><br>My first husband died a few years ago. He had a large pension and also a life insurance policy which I got a large sum of. I also inherited a few million dollars from my mom when she died. I have a small trust for Nick and the rest of my money I intend to leave to my son. I have discussed all of this with Chris, Laura, her mom, and my lawyer. <br><br>Laura’s mom and Laura contacted me last week. They both went off on me. Apparently Laura’s husband saw my post on here and told Laura. Somehow this caused a massive row because Laura and her mom are accusing me of using them for something. I don’t know what. Why I cut them off completely. I told them that I was never close to them and they were never nice to me and Nick so fuck off. Her mom and Laura both called me horrible and told me to just die already because they are going to take their rightful inheritance. I told them they were dreaming and ended the call. I then called Chris and told him what happened. He said he would talk to Laura and her mom. I told him not to bother and if they have anything to say to me they can say it to me. Laura then called me and asked me if we were still going to have Christmas dinner at our place. I told her no. She tried to convince me to reconsider and I told her hell no and hung up. She called back and I ignored it. <br><br>Laura texted me saying I am being petty and I am being a jerk for not letting her family come. She wrote that I didn’t have to punish them for what they did because they didn’t mean it. I wrote back and said they absolutely did mean it and I will not let them in my house after what happened. Laura then wrote back that it was actually Chris who told them I was leaving my estate to Nick and that’s why Laura was angry, and I needed to understand she was angry about the situation, not at Nick or herself. I called Chris and asked him about this. He admitted it. He said Laura wanted to know about his estate planning and he brought me up, and Laura asked about Nick and he told them. He said he didn’t think it was a big deal and if anything it should have made Laura closer to me. I told him it absolutely was a big deal and it was wrong of him to do that without asking me. He said he thought Laura was my family and she deserved to know. I told him that was bullshit. Laura may be his family, but she is not mine. <br><br>I am really pissed and hurt by this. Chris knows what Nick went through. He knows my ex and his affair partner and the rest of his family never accepted Nick. He knows how hard it is for Nick to get basic care. I don’t want Laura and her family anywhere near me. I want to tell Chris to get out and leave me alone but I don’t want to start a divorce battle. I want to talk to my lawyer about this.
