So if your husband had been abused as a child by his mom, you wouldn't be attracted to him because he's not close to his abuser? I have no words. You can't help who you fall in love with or I guess YOU can! Btw, my husband will go see my parents without me and he calls them regularly just to chat. He finally got the loving kind parents he never had growing up in my parents. I can't imagine being so judgemental of him because of his upbringing!
I am attracted to men who like to hang out with their extended families. And to large boisterous, sometimes obnoxious, extended families that hang out together socially and go to each others' kids bday parties and sporting events. That is a lifestyle I am drawn to and really love being a part of. What is wrong with that? What is wrong with me having a preference for my own life? I'm not going to marry someone who doesn't have/want that lifestyle just because I feel sorry for them for not having it - for whatever reason.
Why on earth would I purposely choose a lifestyle for myself that I know with all my heart is not a great fit for me? It's my life and my choice. Now that being said, life happens and things change and there are no guarantees but at least I have some control in the beginning of increasing my chances of sort of having some of the lifestyle I love...
It sounds like you and your DH have found what you love in your side of the family and I am truly happy for you. Other couples prefer limited contact with their extended families for all sorts of reasons and that's a perfectly respectable choice for them, too. It's what works for them.
I do believe that everyone is different and gets to make a lot of their own choices in life.
