"The question is why would the new found lesbian return to see her husband? I'd thought she was in love and happy. It seems to speak for bisexual rights more than lesbian rights."

Oh yes, there couldn't possibly be any reason for estranged spouses to speak, unless they're totally getting back together. Also, there's no way this woman could have married this guy without being attracted to him or in love with him - so obviously she's a "new" lesbian. *rolls eyes*

There's any number of ways this situation could have happened, and you don't know jack about it - whether she was or was not in love with the guy, whether she is or is not in love with the woman, whether she's happy in one situation or the other, and what affects her happiness other than who she actually loves.

Not only that, but bisexual rights ARE lesbian rights. There's no opposition there. She should have the general right to be with the woman OR with the man.

At the bare minimum, she should have physical freedom to go where she pleases with whom she pleases. Ideally, she should face no extra obstacles, legal or social, if she should choose one or the other. And finally, no one should be coerced into anything by threats of self-harm, so I hope she realizes that her partner is being emotionally abusive by threatening to off herself if she doesn't come back.
