<human>: I'm constantly advised just to have sex and don't catch any feelings but part of me feels bad when I'm treated like a blow-up doll, the last man I had feelings for just told me today he was seeing someone else while excusing himself with my age and that we don't live in the same city anymore, I gave him lots of time and he did hurt me pretty often (to the point where I thought I was in an emotionally abusive relationship), he is the first person I slept with and while that's irrelevant, he knew all my feelings and how crazy I was for him just to throw them in the trash for someone else. He knew I admired him and I loved his work he was absolutely fascinating to me and he is by far the most interesting person I've met no matter how conflicted he was. 

I just don't want to have any feelings anymore I don't know how people do to feel happy or even get in a relationship, I gave so much for him and this is how I'm treated in the end.

Can you provide a brief overview of the text?
<bot>: I need advise to get over him and move on since he cheated (because of our "long distance relationship" and age) and I became extremely clingy to him.
