Thanks everyone for the support. I guess that he was trying to keep me around just in case things went south with the person he's trying to get to be with him.
It honestly wouldn't surprise me if he gets in a relationship really soon.
I was very mad for his disrespect overall, so that was just the last straw: what pushed me to do what needed to be done.
I already made plans to go see my best friend today and I will be out of my house most of the day, I need to get some fresh air and good vibes.
