Tough one OP.. but this household>family dynamic sounds similarly to ours in the way that we do naturally spend a lot more time with my family, we go on holidays, have games night, dinner on weekends, trips out ect. I’m extremely close to my family, DH also enjoys the things we do as it’s something he never really did growing up (not saying this is a reason, just that it’s valid to spend time doing things you enjoy)
DH family are quite a bit older than mine, very introverted and don’t have any particular interest in doing much. They pop over for a cup of tea most weekends at some point to catch up and see the kids.
when it comes to gifts, DH decides for his family because he knows them best.. and he often just gets something like a card and some shortbread, never more than one item, never anything of big significance. While I choose for my family and we often do gift ‘more’ to them, vouchers along with a bottle of something they like, or something they’re interested in, we tend to buy a lot of tickets to show and experiences.. but this is just what’s been normal for me all of my life, and DH hasn’t changed his ways since we’ve been together (over a decade)
my point is, it’s not because I like my family more than his; it’s just because that’s the done thing and DH has absolutely no interested making any correlation between what we buy my family and what we buy his 😅
DIL probably does like you just fine provided there’s not been any conflict, you usually don’t just dislike your partner mother for no reason.. so try not to think that or it might come across in your tone/body language to her.
Plus if you want nicer gifts, mention it to DS. Say you’ve got enough photo frame to last you a lifetime, and what you really like is insert wants here
