Nc as potentially outing if linked with previous posts.
Dp doesn't like my best friend. My best friend is also kind of my sister in law (was with my db before he died) and is still very close to me and my family, along with her partner and my nephew (dbs) and niece (current partners). Dp is friends with sil's partner.
My sil will try to arrange doing stuff together and my dp is always really crappy about it. He doesn't control my actions at all and is fine with me going and doing stuff with them but just doesn't want to join us. Sil has never done anything shit to him, he just doesn't like her. Sil also doesn't particularly like dp but she gets on with him okay enough to spend time together every now and then.
I don't mind sometimes doing stuff with them just me and the kids, but I feel like when it's all of us EXCEPT dp his absence is very obvious (especially if he's literally just sitting at home by himself). I don't want to tell sil that dp doesn't like her and doesn't want to spend any time around her because 1. That's just not very nice to have to say is it and 2. I don't want there to be awkwardness any time we are with them because everybody knows that my dp just doesn't like her or want to be around her. And 3. I worry about how it might affect my relationship with sil.
I feel like the choices are to 1. Tell sil he doesn't like her 2. Lie when they ask why he didn't come 3. Dp comes enough for it not to be blatantly obvious he doesn't like her and won't be around her.
This of course is alongside the fact that I don't like that my dp doesn't like sil, and don't want to be limited in what I can do with my family. I want to be able to go for a pub lunch or picnic with my dp, kids AND my sil etc.
I don't want to MAKE my partner spend time with people he doesn't want to, I don't believe that that's right and it feels controlling. But he doesn't actually have a really bad time in their company - there's no arguments, there's some laughter and decent conversation. I think he tells himself he won't enjoy it because he doesn't like her, so is already in a negative headspace when seeing them, but actually has an okay time. We only see them around once a month so it's not like I'm asking him to be around her all the time! So I feel like him compromising and doing it sometimes isn't too big of an ask? But maybe I'm wrong and he shouldn't have to compromise? Would appreciate other perspectives as I'm really struggling with this, thanks very much.
