I've been obsessing over this person on tinder but they just won't message me back.
That's unfortunate, have you tried asking him to meet up?
Not yet because they won't message me back.
I get that you really want to talk to this guy but I think he's made his point pretty clear by not messaging you back. At this point you're just harassing him and you could end up getting your account suspended or something if you keep it up.
I'm going to make a big deal about it and call him names.
I hope you do not really do this, move on and hopefully you can find someone that wants to talk, don't harass this person.
