Family in law troubles

My husband is in the military. So we live quite a distance from either of our families. Neither of us are particularly close with the others family. Anyways his parents are in town for this long weekend. Ever since we got married I have felt unincluded from his family. His dad doesn't even say hi or bye when they arrive to me. And unless there is a conversation already going on that I'm a part of he won't talk to me. His mother is ok. But we're just not very close. Prolly due to the distance? Well it is day 3 of them being here in my house and I am just done. I needed a day to myself. So I didn't get out of bed till after they all left for the day. And then when they decided they wanted to go to a restaurant tonight that I'm not overly fond of. I don't hate it I just don't love it I opted to stay home. Apparently taking a day to myself is me distancing myself from them???? I think it's more of me sticking up for my mental health and knowing I need some time away. Instead of sitting at a dinner table where I'd just be a fourth wheel. They would all talk and laugh and I would just sit there. My husband doesn't seem to notice this tho. Just that I haven't been interacting the way he wants me too today..... I can't win.
