MY GF of 18 months just moved out and I am rereading old text trying to see when and where I started loosing trust. In doing so it's sending my mind to all sorts of places and placing blame on myself. For simply not listening. I learned last week she had feelings for someone with whom she works with, she admitted to me that when I/we lost our emotional connect, She connected with him.

She herself suffers from PTSD from an abusive father relationship.

I know she has already kissed this dude and let him touch her, but that's all I know, she texted her BFF and said all she wants is to get high and have sex, with home or whoever IDK.

Do I need to just accept it and let it go, we have not spoke in a little under 5 days and one text about her mail that has not come in?
