So there is a dude who has been messaging me for like three days. I am not interested. He is. I can't block him, but I can ignore him to an extent. But basically we go to the same social events and we will see each other. A lot. I don't know how to make it very clear that it's a no from me with out making seeing each other in public unbareable. Dude is not HV. He lives with his GF, has a child with her, doesn't work, doesn't have a career or job or anything. Its a HARD no from me. But he hasn't gotten the hint. What would y'all recommend?
