Elephant in the room conversation

I initiated no-contact with my ex for about two months. We were together 7 years (met in our mid 30s) and lived together for 3.5. About 2 years ago I went through some PTSD that put me into a very deep depression. It was hell and my ex suffered for a lot of it. Just as I was pulling through it and starting to get back to normal she said she had enough and wanted to end things. I moved out two weeks later. Since then I’ve concentrated on myself. Went back to the gym, and have returned to my happy old self. I made first contact over a week ago. I used the memory technique. She text back and fourth a bit but seemed cold. I sensed she was angry. I waited a week and I text her yesterday.

I approached it as an elephant in the room. I apologized for a lot. Said I pushed her away due to a lot of self hate and guilt (which is true.). She said she accepted my apology. However, she said this.

“Your apology accepted. But I am far more past what could have been. I learn to set boundaries and to not let anyone take power from me in any way.
You hurt me very badly. Im past it bc I have to move forward …i have two boys to take care of a life to live. I dont sit in possibilities. The chance was there and it was abused and taken for granted.”

She says abused but it wasn’t physical or even emotional. I was mentally ill. For quite a while. I was so drawn into myself I couldn’t see the light if day. Anyhow, the conversation went on a bit more. I explained that our lack of healthy sexual relationship wasn’t due to her, but because I was suffering from mild ED as a result of meds I used to take as well as my state of mind. She said she was relived to hear that because she thought it was her.

We chatted a bit more about the situation but she went on to say this.

“I need space from you bc i don’t belive what you say. That is a condition from what has happened and my boundaries. Not trying to be rude.”

At this point, I’m unsure where to go. Is that the end of the road? Do I just move on or do you see any light here?
