I raised hand as in "hello, I see you and I know who you are!" but nothing more. Not only she said "hi", but she smiled widely at me and that is a big contrast to what happened on previous ocassions.
Now I read an answer to a question around here and the guy said he was still talking to her ex though in a new relationship, just to drop the news to the ex that he has a new girlfriend. He was doing all this to make himself feel better and like he had "won" the break up and make the ex feel even more like a loser. Like "look what you're missing and someone else is enjoying it"
So it hit me... After all the ignoring and running away, the girl smiled back at me bc she had her boyfriend around and I could see she is doing fine, isn't it?
