AITA for not agreeing with arrangements?

[Crazycatlady101]

I'm seperated from my children's dad. He lives with his dad and planned to have the children tomorrow night and Christmas night. His dad tested positive for covid today and still wants the kids to stay there and for his dad to stay in his room. I've said I don't feel comfortable with them staying there (neither does my eldest age 9) and asked to see if he can stay with the kids at his grandfathers house. He's hung up the phone accusing me of ruining his christmas. AIBU? Last Christmas we were all in (seperate) isolation with covid and their uncle spent 3 months on a life support machine due to covid. My dad is unwell as are members of his family.

Just to add my son was really unwell the first time he caught covid.

No YANBU
It's unfortunate timing, and I’d be flexible in terms of rearranging something. But this time, no.

No you aren't. His enjoyment of Christmas does not come before his/ your family's health

YATA (and also UABVVU) for using AITA on AIBU. This is not Reddit!!

@BishyBarnyBee why did you comment

Sorry for the wrong wording... I've never posted before..

I guess I thought I was being mildly amusing. I've never seen AITA on here because it's an acronym used on a totally different site. I thought the thread wasn't so tragic that it would be inappropriate. Was I wrong?

Sorry Catlady, maybe that was a bit mean. I hope you get the answers you need and your Christmas isn't ruined.

It came across quite aggressive😅

My 3.5yr long relationship is under stress a lot of the time because my boyfriend feels like I don’t accept his 17yr old daughter. I myself have never had kids of my own (Im 26, my bf 56). I don’t feel like I can be her stepmom and this situation of “modern family” is not something I ever thought of. He had to spend a lot of the time with his daughter due to his horrific divorce, and later support her when she moved to another school, so from the beginning I felt I’m a second priority in his life (as we had to have a long distance relationship due to these issues). And whenever I had shown my upset about the fact that we don’t spend time together (whole summer he didn’t leave her alone even one night), he would get really upset with me. So the other day when he was speaking to her on the phone it bugged me but I didn’t say anything and I never have (and I understand it’s not a healthy reaction and I’ve asked for more time to figure it out), but he could tell I’m uncomfortable and got really upset saying I still can’t seem to accept his daughter. It’s day 6 and we still don’t talk..
He always adds that he has a great relationship with my family (I also have a great relationship with his parents). AITA?
