I had a relationship for 7years, 5 months ago he just broke up. No reason. We did still talking, not too much at the beginning, we had sex once at march, but didn't get back together. Some weeks ago I understood by myself that he must be in a relationship. He never told me. So I decided to no contact at all, but one week later we met in the street. I just said hello to be nice. He understood that something was going on and some days later he called me on the phone asking what was going on. I said nothing. After that he approched and last week we had sex one time, and in the other days of the week we met. I asked him if he was in a relationship, and he said no. so I try guess who was she. I get a feeling and really had to answer him. He said "yes, she was". She looks like me and was his friend.. I know her. It was so weird, I get mad but than I was OK. He told me he still likes her, that's why he doesn't want to get back with me. Was kind of sad to me, but I'm OK. Yesterday he sent me a messege for nothing, just to say a joke. Some hours ago he sent me a message telling me that he was sad because she's not who he tought she was... my question is: why did he tell it to me? Why me? I know he has a lot of friends to say it, why me? I didn't answer. What should I think about it?

Don't be his rebound. I would simply stop accepting his calls and when he sends you a text message don't open it to read it. Why put yourself through this unneeded stress. Leave him in the past where he belongs and have no contact with his physically or verbually.

Ignore this person completely he doesn't deserve your time. Find someone who will be on your same level, and won't play games with you, which is what this guy is clearly doing.

Give him the cold shoulder!

Just letting you know he is free to bother you again, for sex no less.

my question is: why did he tell it to me? why me? i know he has a lot of friends to say it, why me?? i didnt answer. what should i think about it?
You should feel insulted, and used, that he would think he can come back to you, after it didn't work with this other female.
