Cynthia Nixon’s romance with her girlfriend of four years caught a lot of people by surprise. And it’s no wonder – Nixon had been with her boyfriend for fifteen years, had two kids with him, and had never before been with a woman. But when you fall in love, you fall in love. Nixon says that while she never had any desire to marry her boyfriend, she’d marry girlfriend Christine Marinoni if she could do so legally.

“If it becomes legal, I think we would,” Cynthia tells The Mirror. “It’s something my girlfriend is interested in and it was not something my boyfriend ever was. I think that to get married to her would be a little act of rebellion. It’s like if you’ve never had the vote and then you get it you’re going to run out there and vote.”

Always “very wary” of marriage, the 42-year-old admits she consciously avoided exchanging vows with Danny Mozes, her boyfriend of 15 years and father of her children, Samantha, 11, and Charles, 5, because “I felt like it was potentially a trap. People sometimes want the party, the gifts and the public celebration of this big love – they’re excited about that rather than about the lifetime commitment,” Cynthia says. “So I always steered clear of it.”

She continues, “I had been with men all my life and I had never met a woman I had fallen in love with before. But when I did, it didn’t seem so strange. “I don’t define myself. I’m just a woman in love with another woman.”

Cynthia also said she never felt the need to come out of the closet, because she never felt that she was in a closet. The way she says it is a little unclear in terms of her orientation, but the way she speaks openly about love is really beautiful. She notes, “I met this woman and I fell in love with her. In terms of my sexual orientation, I don’t really feel that I changed. I don’t feel any different than I did before.”

It is interesting that she says she’d probably want to marry, but phrases it, “It’s something my girlfriend is interested in…” instead of saying it’s something both she and Christine are interested in. The phrasing makes it sound more like it’s something her girlfriend wants to do, and Nixon’s okay with going along with it. But obviously if she’s talking so publicly about it, one would assume she’s pretty into the idea. That could make for a pretty interesting reality “Sex & the City” show.
