What am I doing wrong?

For the second time in the past few months I had a girl back out of going on a date last second. The first one I met at the gym and we agreed to go out the next weekend. 3 days before I texted her to confirm and she said she was too busy and never rescheduled. Last week I a matched with a girl on hinge and she said okay to going out. She gave me her number and I texted later that day to plan a place and to meet. She never answered then unmatched me on hinge. I’m not feeling too great about myself right now and don’t understand what I’m doing wrong. Am I replying too quick or coming off as desperate? It’s not like I’m replying right away and the girls seemed so interested at first. Thanks
