@Jnc1207,
It's not hypocritical for you to date other guys. You don't have a relationship with this guy.
And you don't need to ghost him or play any little texting games.
"Here's when I'm free to meet up. (list three days) When are you free?"
That's your next text^, assuming you still want to meet up.
If not, you can either stop replying or just write one last time to say sorry, you'd rather not but you wish him well.
And... that's it.
PS Back in the Stone Age, when I was dating (and right around your age, heh), I did the personal ads scene. I dated, I want to say, 40 guys. 50? Before I met my husband. Until I met my husband, I had no ties to any of them. We would have dinner or drinks, might kiss, might have a second date. I think I hit a third date with 2 of them before meeting my husband.
It wasn't mean, hypocritical, loose, bitchy, whatever pejorative your circle wants to toss at such behavior. It was a single person enjoying being single.
You're allowed to. Not every dinner or meeting has to be fraught with meaning or leading to marriage or even dating. It can just be... a dinner.
PPS I realize you have anxiety, but you're setting yourself up for more anxiety using Tinder, seeing as the point is to meet new people from online, which you say worsens your social anxiety.
So you might want to find a better way to meet people.
