So sorry tomjon78, its hard to come out of these kind of unhealthy relationships
I can very much relate with codependency and that it goes glueless together with a unhealthy rs! Sometimes life provides us with hard learning stuff :'(
I think it is good you can aknowledge your feelings of anger, disappointement and frustration. Sounds very much like step 1 of the five steps of grieving.
I´m trying my best, reading about this condition and see my therapist and try to work out and be positive. I avoid alchahol but feel sometimes very bad when I´m alone and my mind wonders about our relationship and frankly I feel very fatigued and frustrated and cheated.

for workout, T and avoiding alc. Try to wonder not too much about the rs or what you could make differnt looking backwards.
I would not contact her right now. She seems to be doing things to cross your path. Contacting her would send her false signs. Its good to post here when you have the urge to contact her.
