I don’t think you should tell her your feelings. I know you’re anxious that she’s meeting with her husband and you don’t want to lose your advantage, so you think that telling her your feelings will put your chip on the board and give her something to look forward to, but the reality is that she’s in the process of a divorce and it’s much better for her (and for you) if she decides to divorce her husband and goes through with it because of what happened between the two of them. You see, if she divorces him because of you — and the two of you have a fight or things start to go sour in a relationship you may have with her, she’ll look back to him as a saving grace because she’ll think she left him for you. But if she left him on her own and divorced him on her own, she’s going to start dating you, when she does, because she’s single, free and wants to be with you!
So hang tight — you’re interested in a married woman who is trying to get divorced. Let her. Don’t interfere. And when she is you’ll feel much better about the two of you. I hope that helps! 🙂
