My ex and I have stayed in touch when I think it's bad for me. The upside for him is I think it eases his guilt and maybe he feels he will eventually get me in bed again.
I keep him in my life for comfort, he was my best friend and we know each other better than anyone but I believe he would drop me in a second for someone else who gave him attention.
This time last year he treated me badly, cheating on me and then leaving me when I 'freaked out' about it. I tried to repair it with him but it was like he couldn't handle my challenging of him and he disappeared but recently came back into my life. We haven't slept together but we've met for coffees and we chat on the phone.
I love him but this is the week last year that he cheated and it's full of memories. I reminded him of this, telling him I was somewhat dreading this week because of memories and I think I want him to 'reach out' and check in with me. I want him to see how I am so that I know he actually cares.
