@Its_just_me while I get it’s hard to be harsh and straight up with people, he sounds like he can’t take a hint. Spam calling someone when clearly they aren’t texting and not interested is honestly just impolite and childish, and would annoy the hell out of me. He wasn’t nice to you, and you don’t owe him anything. I’d send a message that’s clear and polite, not harsh or mean if that’s what’s stopping you. You can literally say - hey, I’m not really interested in pursuing anything anymore or chatting. Don’t take it personally, I just don’t think this works and I’m just not feeling it anymore. Hope you have a great day.
Or something.
You get what I mean
