Sad..

Is it wrong of me to feel sad to think my ex will someday have a baby wth his current girlfriend who's just disgusting period. He cheated on me with her after I had an abortion, he wasn't supportive of the abortion then cheated on me with her for a while after it happened, then ended up giving me an sti later on when we broke up after I found out about her. I just feel cheated in general with that relationship.
