This could end up being a huge long post, so I will try to keep concise.
Basically, my partner and I have always had a really good relationship with his parents - we would socialise a lot, go on holidays together etc... until a few years ago. I can't really go into the details of what happened because it's a very specific situation and would definitely be outing, but something happened which drove a really big gulf between us.
There hasn't been a big fight but there is a huge difference in opinion and that we have basically agreed to try and put behind us because we don't agree. The thing is though, our relationship with them hasn't been the same since.
We still see them from time to time, mainly significant events like birthdays, Christmas etc. We don't go on holiday with them anymore and we don't get involved with the activities they do with the rest of the family (quite a large, close-knit group). Of course, that's our choice to not participate... but it's still hard, especially for my partner.
I don't know what I'm posting for really. Maybe some advice? Has anybody been through a similar situation? As I said it's been going on for a few years now, but we saw them last night and I just felt so shitty the whole time we were there. My partner and I do talk about it but they are his parents. It's very sad really.
