Being Dumped Sucks

Well, I have one, I found out my GF was cheating on me with my bestfriend, I was mad, I was furious at the time I found out, but I thought to myself, instead of making it a big deal, I just told her I'm breaking up with her and walked away. Of course, after that, I met her a couple times during a few meets with some friends, but I wasn't really angry, more of me thinking what I did wrong to have her cheat on me.

I realized after a year of finding more about myself that it wasn't really me, but people do change in the span of time, as they gain more experience in life they change and develop who they really are, whether they could be evil or nice or peculiar or anything, it's just a matter of time.

Tl;DR, well, You break up, you think about it, you realize that people change and sometimes it's not really your fault.
