I have recently split with my ex we talk on the phone and have a laugh sometimes he keeps asking me if I have slept with any one it's been a month now and I'm still hurting.. he says he can't talk to me on the phone long as all the feelings come back and he thinks about things is he over me or isn't he I don't know what to do

You just go NC and let him come back to you if he wants a relationship of not you must move on seems like he is playing around w your feelings.
