<human>: I am an 18F and dated a 22M for 5 months. My ex always had trust issues (all of his past gf had cheated on him) even though I was a completely loyal girlfriend. Our relationship was a lot of fun and we had many good times together. At the end of the summer he broke up with me because I left to go dorm. Even though my school is only an hour away from home, he said he didn't want to do the long distance thing again. He said that we could still hang out and that nothing has to change other then not being in a committed relationship. He broke my heart. I told him that I needed some space for a bit. Next weekend we both end up at the same party and he is with another girl(I somewhat suspect he might of been cheating on me with her for a little bit). I handled the situation with grace and maturity. It isn't long before they are in a relationship together. I still talked to him maybe once every week and 1/2. Then we ran into each other at a party last friday. 2 days later, he tells me he wants to chill and be friends. What is his angle? Should I go chill with him?

Can you give me a shortened version of the text?
<bot>: He has trust issues, broke up with me when I went away for school. Started dating another girl almost immediately. Ran into him at a party last weekend and now he wants to chill again. What does this mean?
