That almost sounds like my wife and my last girlfriend. She lived as a lesbian (our girlfriend) for about 4 years, and was actually living with a woman. They even did a commitment ceremony. Then, they split up for some odd reason. Well, our GF met up with us and claimed to WANT to live and have a relationship with a couple. It didn't work with us, but we hoped the best for her. We liked her, but she had some....issues.
There is a lid for every pot...Sometimes even two or three...
