I need someone to explain this. How is it that the guy I used to know who was the most toxic, type of player talking and sleeping with many girls and was so rude to me and trying to also sleep with me now has a gf. What is the science behind this other than he wasn’t serious at the time. It baffles me who would ever want to go for a guy like this? He probably was the complete opposite to her than he was to me but yeah. How was he so horrible but now is dating? I thought people like that would never find someone. I’m single because any situation like this I left when I realised I deserved more.
