He said that he doesn’t want to initiate any type of friendly contact or gestures such as conversations or lunch ‘dates’, etc. because he doesn’t want to provide me with a false sense of hope. He doesn’t want his friendliness, for a lack of a better word, to give me any type of hope that our M can be saved.
I think having hope is just fine. It's human nature. But I also think he's being very clear as to not wanting you to get ahead of yourself and think 100% you guys will work. So yep, focus on the here and now and GAL. This very evening, do something that you like. Hugs.
