So, before reading this I want to make it clear that I am NOT looking for any sort of judgement here just merely an answer to a question with a reference if you can cite it. I am a bisexual female, I have a husband. I also at the present time have a long term girlfriend. In instances of marriage is it considered unlawful to marry her if we wanted to do such? The legal term for bigamy is having two husbands or two wives at the same time, but this situation doesn't quite fit the category although I guess if you generalize it then it could.
