<human>: Two days ago I broke up with my boyfriend of four years when I found out he was playing me and a girl at his college.
Honestly our relationship wasn't working out before I found out and I was planning on ending it but I loved him so much that I held on, until I found him messaging a girl on the iPod I lent him.
We had a lot of issues and I rarely felt my needs were met, so I know that the split was a good thing..

The problem is I find myself absolutely miserable over the fact that he hasn't tried to contact me in any way or apologize or something.
I thought that after four years he would do more, but I guess now im realizing he never really loved me..

Can anyone who has been cheated on, or possibly experienced what I am now, give me some sort of advice of how to stop missing him so much.

Can you condense the text into three sentences or less?
<bot>: boyfriend of 4 years had a girlfriend at college, I had no idea, neither did she. I can't shake how much I miss him and us, but I am so mad at him too, what can I do?
