One hundred percent this, a lot of the boomer generation was raised on this notion that "you always support family" and it's bullshit. I was raised with the notion of "you don't have to like them, but you do have to love them." My own mom, weeks before my wedding, freaked out on my wife and told her she was "tearing this family apart" over some stupid inconsequential thing. We're talking so minor that her or I don't even remember it.

My wife and I took none of that shit and threatened to cut her off, cancel the wedding, and get married at the court house. She screamed, had family call us to tell us how shitty we were, would call me directly to tell me how bad my actions will hurt the family, etc...we stuck to our guns and my wife FORCED her to apologize before we agreed to come back. My mom was right, we didn't have to like her but we loved her enough to give her a chance to fix her wrong, which she begrudgingly did.

All of this happened behind closed doors and only a handful of individuals know this happened. Now my family respects our boundaries because they know that their bullshit generational notion is exactly that, bullshit.
