The reason I continue to be polite to him and not just block him is because I want to be mature about it. If I still loved him, this would've been too painful and i would have to completely end it with him.
I could be like "uwu you make me too sad.... I'm still not over you so I have to block you..." but i'm more like "it's fine if you want to msg me every now and then.. I don't care"
