Actually, yes, she has made her preferences (at least up to this point) known, at least to me.
She is not interested in anything further than friendship with M, because she does not like his lack of respect for others' feelings, or his inability to be open with everybody. She WAS interested at the very beginning, UNTIL she found out about his compartmentalizing, etc.
She is possibly interested in H, still trying to find time for them to be together alone to explore a little more freely.
Me: married to H for 14 years.
M: Boyfriend of about 1 year.
M2: Boyfriend's girlfriend of about 5 years, and a good friend of mine.
