Not truly being clear when breaking up with someone shows a lack of respect for the other person. Do yourself a favor and let it go. If you don't hear from the other person, take it as a sign that it's over.

It's tough when you break up with someone and they don't even want to be friends anymore. It's true that continuing contact can make you believe or want to believe that it isn't really over but I want to feel that my ex girlfriends really did care for me and still do even if they don't think that we should be together.

I had an ex that constantly broke up with me and when she had definetely decided that she didn't want to be in a relationship with me she still kept showing up at my door saying that we were friends. We kept dragging the relationship and what had happened between us up and the physical atraction was still there, so it developed into a "friends with benefits" situation. Well, she had always been breaking up with me and getting back together during the relationship and telling me that I didn't own her and stuff like that, so I didn't accept that it was over however much she told me that she didn't love me and that she was just being nice to me because I was lonely. It was only when she started seeing somebody else and it hit me that she was really in a relationship with him that I decided to tell her that I wasn't looking for a casual relationship and that I didn't think that we should see each other anymore. And yes, I told her to her face.
