My and ex-DP were together for 3 years. No dc, although I have a ds from previous relationship who ex developed a very close bond with. I split up with him in June- we would argue a lot, there were other issues with our relationship such as him being lazy/not getting a job or learning to drive etc. I began to not fancy him anymore. He has since been staying with his parents a few hundred miles away, but is due to come back "home" (we do not and never have lived together, but the same city) this weekend. I haven't seen him since June.
I have been thinking about him a lot as his return is imminent, and considering how he will eventually meet someone else. This just kills me. And I am confused by the extent of my emotions regarding the thought of him meeting someone else and what this means about my feelings for him. Is it just a case of "I don't want him but want no one else to have him" or something more? How do I fully establish my emotions towards him? He still wants to get back together, but I don't know how I feel. Any thoughts would be greatly appreciated.
