Simply goshawful! This is what I would do. I would begin volunteering some place for returning vets who might have been injured, have no close family, and are struggling. I would also possibly volunteer at a child's center, teaching a child to read, working with a small group of kids to play simple games, whatever is available. I would not call them if God knocked on my door and asked how they were. If she is Chinese, as I think she might be, you'll find they often have a thing about the males or sons in the family, even in this day and age. I know this from experience. Obviously, she's not much fun because even your son felt controlled by her and wanted to leave. If they contact you, I would be pleasant, even cheerful, and I would reveal nothing, unless you have to, of what you are doing. I would ask only general questions about their life. If they want to get together, I would make a moderate effort to do it on their terms, but I would get some of my terms in first, and I would definitely not go out of the way. I would do other things to add other people, friends to my life. We all need to feel needed. I recently had two knee surgeries and was wobbling around. When my grandson showed up for a two-day stay, I was able to kick it into high gear and work through the pain to cook for him and do his laundry and spend time with him. He was quite grateful, and I did it all willingly. I do have a member of the family who is very difficult and, in order to make things work in a lot of different directions, my husband and I have gone way out of our way. The last nasty encounter was the last nasty encounter, if you know what I mean. This person is now persona non grata, and I have made up my mind that nothing but an abject, in person, most sincere apology would make any difference. You sound perfectly reasonable to me, and I would get busy aligning myself with and getting to know other perfectly reasonable people who might be more appreciative. I hope you have gotten your money back. In Good luck!
