Misssy2, your post resonated with me. I "lost" a friend of many years and dont know what happened for him to shut me and DH out.
Ive tried to reach out several times but no response.
Ive had to accept that I wont ever know "what happened" between us.
It is very hard to deal with but does get easier bit by bit.

It must be even harder losing a therapist.
Best wishes Stahrgeyzer.
