I've been married for over 16 years. I got along great with my in-laws from the beginning. Father-in-law died 9 years ago. I had a situation with my mother-in-law two years ago that basically caused me to write her off. I flew into Buffalo for my mother's funeral and planned to rent a car for the few days that I was going to be there. M-I-L told me not to bother, that I could use her car while I was in town. I said O.K. Had a friend pick me up at the airport and take me to her house. As we arrive, she's walking to her car with her boyfriend. Smiling and laughing, she shakes the car keys at me and says "I bet you want these, but you're not getting them. We have to go to the reservation for cigarettes and have some other things to do." It was one of the most bizarre situations that I've ever experienced. I assume that her boyfriend had influenced her decision, but I just said "whatever" and left. Haven't had a conversation with her since.
