Urgent Opinion Do EX's Ever come back?? Yes or No?

met this guy around 10 months ago. We gelled on an intellectual level & clicked right from the start we were like best friends as well as lovers while seeing each other. But i discovered over time that this guy wasnt ready for anything serious. or any proper commitments right now, so I decided I was movin on as we were on 2 different levels right? he would still call me etc. We had a few serious talks and he said to me that i am a good looking, articulate, intellegent woman and that I have fantastic qualities but a relationship is just not what he is looking for at the moment with any1 as he needs to sort himself out etc and that he wont have enough time to be attentive to any1, we have no longer been intimate, but he still presses the fact that we work things out as I just want him out of my life to move on. I know no doubt that he cares for me a lot, I dont have to question that as we have been through so much. He has even said to me that it is his LOSS, as I am an et & quality.
