The dumpee :(

Well I dated this girl for 8 months and we had our fair share of problems and I had been sexually abused by my elder brother it came back to haunt me in the form of PTSD and I am currently working through lots of anxiety in counseling. This has caused alot of stress in the relationship we had. I would get frustrated quickly and sick often, but I tried and things were starting to get better in my opinion, but then she broke up with me after she left my house one day which sucked. It was one of those slow processes that hurts. It was a little over a month ago from now. I know I didn't give everything I could of in terms of romance and emotions, but I have been getting help since then. I cut out the obsessive behaviors I had since then so I have been making progress. So I saw my ex a few days ago it was for a nursing school assessment (she assessed me because I agreed too it while we were together) and she complimented me A LOT was flirty and asked if I was with other people since we were together. After the assessment was over I asked the teacher if I would get paid as a joke she said no that my ex would have to take me out to eat. So I laughed and once the teacher left my ex said that's not happening. I am confused by the signs that I got. There was lots of serious extended eye contact and interest, but I don't know what to do. Wait a little bit and ask her to meet for a bit like coffee, then take it from there, call her, or should I not do anything and move on? I don't know if that would be lacking self respect if I do so. I have went without talking to her and reflected on many things so if by the tiny chance that we got back together (and for my future relationships) I would have learned things such as loving her the way she wants to be loved, cutting out my unattractive behaviors, and working on myself a lot through counseling and exercising. She tried to text me once but I ignored her because I recalled how she told by dating my she would be settling. It's been 8 months and I haven't given her my best she told me. I thought I was doing fine on moving on but I had a dream that she cheated on me or was fucking someone else and another dream where we were together or hanging out. Now it's bothering me again because of the dreams I really think I believed in this girl a lot more than anybody else which has me stuck on this... I also figure that everybody is going to hurt so I can forgive her for telling me things like that and not coming out with the truth, but then again of course I don't want this scar to keep getting reopened.
