I'm Tired Of Him Playing With Me ...

I will try to be brief - I am currently 20 years old - 5-6 years ago I met a 30-year-old man on Facebook and 3 years ago we became boyfriends. In the beginning my age was a bit of a problem, but 10 years is a difference ... it was my first ... we were together for 5-6 months and then we started to separate and reunite and so on for 4 years .. in the last 2 years ago he started looking for me only for sex but without love and when I told him no - he blocked me and after less than a month he looked for me again .. I still love him and I don't mind getting together but he has no feelings .. and I want sex but without feelings what is it? During the time we were separated I was not with another ... but just when he writes to me or calls me and my memories come back and then I feel sick for 1-2 weeks ... my question is how to forget him I'm tired of play with me and make a fool of me ...
