What should I do if I am played by a married young woman? I hate that she makes me like her, and now she ignores me, doesn't answer the phone or return messages.

You know she is married, and you like her without hesitation! Before you start, have you considered where you are better than her husband! Except younger. She liked you at first, probably because she was in a tired period in her marriage, and her inner impulse to find novelty prompted her to start with you, but after a period of time, the novelty disappeared and she would slowly return to her family. I think you are still young and have a lot of good times. Treat this relationship as an adult game. The game is over. You should live a normal life. There is nothing to complain about!
