I've always thought that BIL doesn't like me and we have had two small arguments in the past but they were nothing major and were like 4-5 years ago. DH always insists he does like me. BIL and DH are not that close because BIL doesn't make much effort to keep in contact with DH (we live in different cities). DH and I came back to our home city for the Xmas period as DH managed to get some time off work for it, DH contacted BIL about meeting up over Xmas and BIL said he wouldn't have time to see him unless he could swap one of his shifts (bearing in mind he has a number of days off...). Anyway BIL managed to swap the shift so invited DH to go round to his house. BIL got married in summer and moved into the house with his wife a few months before the marriage, DH has been over there a couple of times but I've never been invited. DH suggested that BIL invite their cousins round as well - they are all male and younger than BIL and DH. I thought that was nice for them to have a day together. DH went and spent the day there, but then I found out that in fact BIL's wife was also there (not a big deal as it's her house and she finished work early), BIL had also invited his auntie and uncle with the baby girl cousin, as well as the partner of the only other cousin who has a partner and they're a few years younger and have been together about a year and are both at uni elsewhere normally. So basically everybody else was invited except for me. DH didn't tell me, I found out via photos posted online, I was obviously very upset and also upset that DH didn't call him out on it or anything.
DH is meeting up with BIL tomorrow and says he will talk to BIL about it tomorrow but I don't really see the point. I mean it happened, it was days ago, so if DH had been so bothered surely he would have brought it up at the time? And I don't want them to have yet another argument that will be pointless. DH said it is important so it doesn't happen again in the future, but I can't see it happening again anyway as we don't even live in the same city so don't see them that often and they rarely invite anyone over to their house anyway from the family, and even if they did invite me in future realistically I wouldn't want to go after being publicly humiliated like that.
Should DH still talk to BIL? What should I do in future if I am invited to BIL & his wife's house (unlikely lol)? I'm not going to argue with them or anything but I am very very hurt and feel like I've been snubbed so badly and in a really nasty way.
