Exes never get what they deserve.

I was with this guy for 4 years and throughout the whole entire relationship, he always had other women on the side and he emotionally broke me. I was young and didn't know my self worth back then so I accepted it. Fast forward to now, we have been broken up for months, and now he has a new girlfriend. He cheated on me with her actually, and she knew about me. They seem perfect and she's gorgeous. While I'm here still struggling with life and new relationships. He always seems to win in the long run even though he caused me so much pain. Do you girls have any encouraging words?
