<human>: Can you provide a brief rundown of the text in within 3 sentences?

My first relationship lasted 2 years but during at the end of those 2 years things started to be boring and I couldn't be bothered anymore. We skipped to seeing each other and then I eventually broke it off when I found someone who kept making me smile, well things with this person who we'll call John, ended badly and I started talking to the first boyfriend, again(we'll call him Peter). The thing is, Peter found a new, younger girlfriend who he's been dating for a month. I ended up meeting up with Peter and let's say he cheated on his new girlfriend with me... don't tell me how wrong it is, etc, I know... that's not the point of this post. :c

When I first ended things with Peter and got with John, Peter went ballistic, he couldn't stop messaging me and black mailing me. But now, I can't get over Peter. He's always on my mind and I just want to talk to him all the time but he seems so uninterested but it just messes with me the fact that he met up with me and made me feel like I was his again? I just really want to talk to him and tell him how I still feel but he's all over this girl he met of Facebook which lives the other side of the country. Ugh. 

Just, what should I do now?
<bot>: 2 yr relationship ended because I got bored, got with someone else, ended badly, have feelings for first boyfriend, but he has a new gf now but he keeps messing with my head. What do I do?
