I was engaged to a guy and took him back after he smurfed over my child (Im a dumbass). He took advantage of the situation of me having a brain injury and once I put smurf together I was done. I left him and never even CARED we broke up. You move on, you find better.
I then found my SO.... we had dated previously but went back together, and recently broke up again (and its smurfing killing me). We never got engaged and he means more than that dude I was engaged to.
