hi, I have the same experience. I'm still suffering from that now.My ex broke up with me cause we have no same future. And we still see each other very often , having sex.He treats me very well apart from that he doesnt want going out with me with friends.He thought that will make our friends think we are still be together thought we are doing exactly same things as we did before.
Sometimes, I still think I am used for sex by him.It makes me angry and sad. I tried to think it possitively. Now, I give myself chances to meet new friends and move on.And at the same time, I keep this unhealthy relationship with him because I cannot help tp say no to refuse him.That is very bad. But it is the way I try to cool down myself slowly.
I really understand you.
