I am feeling exactly the same. I think about her all the time and I am not making any progress. In fact, I am in a far worse place now than this time last year I think. I am in a lot of pain and turmoil regarding the maternal feelings and needs and I know I can't have what I need. She has acknowledged this and said that she can't be the person (mother) i so desperately need but that she wants to support me. But her not responding to texts, ending bang on time, no touch etc just seems to make this so much worse and highlights my needs for which I feel very ashamed.

I text her last night in a moment of desperation. I was really desperate and in a very very bad place. She has responded this morning with "see you next week" what is the point?

How can I think less about her and how can I get over her/move on?

Should I quit?

I'm sorry - I don't mean to hijack your thread,I just relate so much to this.
I am sorry you are struggling and hurting too. This is so raw and painful.
I'm sorry.
