My theory is that the 500+ matches are the reason you're not getting any dates.
How can you even know who to talk to? Too many choices, too much stimulation, might lead to lethargy.
I would go over the matches now and see what's going on, try and gauge what your looks level is.
Then, delete your tinder account and start over. You'll still have all the same data, but your swipes will be reset, and other people's swipes of you will be reset.
Once you get to 15 or 20 matches, stop. You don't need the increased validation of more swipes. You cannot possibly go on a date with 100 women fast enough for it to be matter. Once you're at a dozen or so women, talk to a few of them, and after a couple comments just say "Sara, would you like to meet for a drink later this week?"
