Your FOO had expectations of you, that were impossible for you to comply with. (Literally) I am not sure why they do this? Why they can't see the damage they caused?
Living with CPTSD is a very challenging life to lead. You always stay a kind and true person. Papa bear is Papa bear. He has his own needs as we all do. It is never easy when our needs are not being met. He seems to offer your needs as much as possible for him. He sounds a good man.
I recently have felt lonely. In need... Strangely, not from others though. Others give me a fair share of their time. My needs are a personal with myself, i think...
I really struggle with self love, respect and compassion. These are skills which can help when others are unavailable or we require some alone time.
I send you hugs, respect and empathy
