Question on in laws during DB.

Been doing pretty good at detaching from W here lately but with me and inlaws its like nothing ever happened. FIL is not doing great and wont reveal his test results he has been having. I prepare his taxes and went to get his docs yesterday. He asked me to be the executor of his estate and hinted at leaving me something. I told him he will figure it out after I get his taxes done. I said that to buy time. Should I politely decline or is that too weird? BIL has been asking me to help him drive bc he has a permit and has two weeks to learn how to drive so he can go to college. Don't see that happening but story for another day. I asked him to ask W and he said she's too mean.

Should I try to get away from these folks while DBing? They always liked me a lot. They obviously love W but says she is too mean and starts stuff. Them saying that has also helped me learn that yes I been hung up on being a distant husband but the street goes both ways. She isn't the easiest person to get along with.
