“Hopefully everyone had an in-law drama free Thanksgiving, I know I did!”
Sure did! All my conflict was with blood relatives. 
My MIL and her son, my BIL were sniping at each other. But fortunately no one got caught in the crossfire.
You will likely be a very understanding inlaw to whoever will become your DIL.
One of my coworkers went home for TG by himself without his live-in g/f. He told me his g/f was very upset.
We may be in the same situation (if not already in this situation.)
It’s threads like these, and forums like CC, that teach me the correct way to behave.
And its threads like this that make me thank my lucky stars…
Don’t know what will happen when s#2 marries, but at present, things worked out great!
My MIL is my biggest fan. My own mom sees all my flaws; my MIL thinks I’m an angel. Hopefully I can keep this going!
My kids have both remarked that, based on the way I treat their boyfriends, that I should be a really good MIL. I just think they pick especially nice boyfriends. I’m looking forward to being a MIL someday, despite the poor relationship I have with mine.
I liked - truly liked - my mother-in-law and father-in-law (both deceased now) and they liked me. I don’t have a particularly good relationship with my husband’s brother - something passive-agressive going on. He ignores my presence until he can’t … i.e., I engage him in some way, then he responds politely. Not sure what I did but I no longer enjoy his company. Imagine having a guest in your home for the holidays who speaks to you as little as possible. I will say he dislikes his only other sister-in-law more … nothing passive-agressive there … everyone knows he can’t stand her.
Truly like my son-in-law and get along well with him. However, he’s married to the daughter who regularly gets furious at me or her father or sister and brother and quits speaking to whomever for a while. It’s an assbackwards way of having an in-law problem.
