TL;DR - FH doesn't like attending family events with me/acts like it's a chore. I expect him to come to them with me as my partner.
I come from a very tight-knit family. We are all up in each others' business (the good way) and love spending time with each other. We are always celebrating the little things in life and regularly see one another (we're only a 10-15 min drive from my side of the family, FH's family live 8 hours away).
FH grew up in a rural area with only his immediate family. His family are completely different to mine, aside from the geographical distance, they aren't as open toward one another and are generally more quiet and distant. I.e. I call my parents daily/every second day, they speak to each other once a week or less.
Since FH and I started seeing each other years ago, I was always conscious of the fact that my family's craziness is not what he is used to. Because of this, there are a number of times I see them on my own, which is totally fair.
With that said, he always acts like I'm asking a lot of him or that it's a chore to come see them. For example, we last saw my parents (together) on Oct 2 when we all went out for dinner (I also on my own see them weekly when FH is at football practice). I found out just now that my sister's boyfriend is coming over tonight to meet our family and they've asked if we want to join. She's 16 so it's not serious (at least not yet) but I thought it would be nice for us to both go over and be part of their pizza/meet-the-boyfriend night.
I told FH and he said he feels quite tired/flat. I said we didn't have to stay late, and if he wanted to bring his own food instead of pizza he could (he's quite health conscious). He doesn't 'really feel like it' and I could go alone. I told him I didn't think it was that big of a deal since we're staying home tonight and didn't have any plans to do anything. I am totally ok with him not coming to everything but it really upsets me that he doesn't see the importance of family things the way I do and doesn't want to make a slight effort to come.
AITA for expecting this of him?
