There's a backstory to this which is a lifetime long so I'll summarise as best I can.
My mum is a manipulative person and has always been emotionally abusive to me. I'm one of her 5 children and she has a bad relationship with all of us. You could say my dad is her enabler, but he is actually a lovely person who has made some questionable choices (such as standing by her) but I believe a lot of that is down to the abuse he's suffered from her over the years.
I could give you a long list of things she has done to me over the years which would shock you but I'll not go into all that right now as I don't want to drag this out.
Basically, things came to a head this summer. It was my sister's wedding weekend. I like in the south of England and I flew up alone with my 2 young children. When I arrived, my mum had set the bedrooms up differently to how she normally would. She had put the cot up in the room that my older DD was going to be sleeping in. My younger DD is a nightmare at sharing a room, every time we've tried, she's take literally hours to go to sleep. My eldest is also a very early riser so I knew she would wake early and then wake my younger DD. I explained to my mum and asked if I could just put the cot in the room with me (there was plenty of space). My mum hit the roof about how ungrateful I am and that his her house and I should be thanking them to putting us up, not complaining. The upshot was that I wasn't allowed to move the cot. That night went exactly as I'd expected. The kids didn't go to sleep until almost 10pm (normal bedtime 7.30) and we're both up before 6am. I had 2 vile kids the next day. They were completely and utterly exhausted and every small thing became a huge challenge. The next day my sister arrived and would be sleeping in the room next to my girls room and the following morning was her wedding day. I was so worried that the kids would wake her up in the morning. My older DD has a grow clock so if she's in a room on her own, she wouldnt get up before 7am and youngest DD is a great sleeper so I knew she'd sleep a full 12 hours at least if sharing with me. I was also concerned that on the wedding day they would both be exhausted, grumpy and uncooperative. I was bridesmaid and so I really needed them to be on good form for the wedding.
I called my DH in tears because the whole situation was becoming so stressful. He told me to tell my mum that if she wouldn't just allow me to move the cot, then I would be booking a hotel for the evening. She once again went ballistic at me, calling me names and saying I was blackmailing her. I categorically wasn't. I was telling her the truth. I wasn't going to stay there another night under those circumstances. My mum said to me that I just want everything to revolve around me and that I was obviously trying to ruin my sister's wedding weekend because I was jealous of her. She said a lot of very hurtful things.
Eventually they let me move the cot and, lo and behold, the girls slept amazingly that night. As did my sister and I. The wedding all went smoothly so i was very relieved.
After that though, I came to the decision I couldn't stay at their house on future visits to Scotland. Stuff like this happens every time but I believe my mum was worse because my husband wasn't there with me. I was more vulnerable.
Anyway, things turned really sour when I said I wasn't going to stay with them on our next trip and lots more was said. At one point my mum actually called me a rat infront of my 5 year old DD.
I stayed with my lovely brother and his wife and had a lovely trip. I only saw my mum once and she spent the whole time having my eldest on her lap, sort of whispering into her ear so possibly bad mouthing me.
Anyway, we're heading back up to Scotland in a couple of months and I received a text from my dad saying to remember we're very welcome to stay with them when we visit. I sent a very nice reply, thanking him but explaining that a lot had been said & done which I'm sure he understood, and I thought it would be best to stay elsewhere but spend a lot of time with him and my mum and that we should just take things one step at a time and that I was really looking forward to seeing them.
I then posted on our family WhatsApp group to give them the dates we'd be visiting and asking them to let us know when they're free.
I received a message from my dad (written by my mum) which basically mirrored the message I had sent to my dad saying "these arrangements aren't good for us, I'm sure you'll understand. A lot has been said and done and I think it's best if we visit you at DB & SILs house". So basically I'm not allowed to go to their house when we visit. My D.C. haven't seen their grandparents for 8 months and probably won't see them again until the end of the year. I didn't want to drag the kids into this. DD absolutely loves "grandad garden" and has been talking lots about going there and now I have to tell her we can't go.
AIBU to be upset by this? Am I dealing with this the wrong way? I just feel so lost.
