Fall in love with a married woman, she just wants to be friends with me, and she will reply when I send a message. I can't be ambiguous, so I'm in pain.

You both have problems. Why do you know that she is married, and you want to interfere in other people's marriages and ruin other people's lives? Now that she knows that you are in love with her, she doesn't want to divorce for you, which means that she doesn't love you. Since she doesn't love you, make a clean break. She is willing to make friends with you and return your messages. She eats in a bowl and watches in a pot. Her motives are not pure. You all take care of yourselves.
