Does she have secret feelings for me even though she has a boyfriend?

There is a woman who I recently told I had feelings for her. I told her I can’t cross the line since she already has a boyfriend. She did say she was glad I told her, but he will not want me to even associate with her once he finds out unless it’s a group event. Does that mean she feels the same way and could be an open door in the future? Again not trying to break them up, but wanting to know if she feels the same at heart?
