<human>: I'm feeling a little lost lately. I was with this guy for 4 years. the last few months were a little off and on. but for about the last month we weren't dating, he made that clear. But he still always wanted to hangout, so we did.

I had talked to him about what if i move on, what if i start to like another guy? and he told me he didn't care. that we would always be friends and he'd always be there for me..

so he invited me to this party where he completely shrugged me off and ignored me to flirt with other girls. so i started talking to a guy that was obviously interested in me and as the night went on the flirting got more intense. He walked me home and then things got a little hot and heavy.

the next morning I informed him of what had happened that night and he blew up and said that i broke his heart. He told me he never wanted to talk to me again.. now, a week later he already has a new girlfriend, already had pictures on facebook of them kissing. so obviously I didn't really mean much?

I don't even know where to start. I kind of got lost in our relationship, I was a horrible friend. so now I feel like i have nothing. I am far to socially awkward to even meet new people.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: We weren't together, i hooked up he got mad doesn't want to see me ever again. he already has a new girlfriend. How do I move on?
