I'm in my 50s, she's 35, hot and she knows it. We hung out once or twice over drinks and kissed a bit. She'll text me and ask what I'm doing, then not reply until days later. It's inconsiderate and I've tolerated it, but need to communicate to her that I'm not going to stand for that kind of flakiness. How should I word the message if she texts me again? Everyone has a different opinion.
