It's not wrong to feel whatever you feel. It's understandable but you don't need to act on your feelings.

The guy is impolite and not considerate plus he doesn't seem to be interested in you enough ( you are the one asking him for the phone number and you are one asking to meet and when he isn't rescheduling you are the one to ask what's going on)-those are signs of him not being that interested and rather following your lead. If he gets back to you I honestly wouldn't continue with him but politely tell him that you aren't interested and move on

You deserve way better and you should go for it!
