Hmm, I admit it's hard to say, but personally I'm not sure she can love you in a romantic way. Maybe she sees you as a very good friend and that's why she's acting in a way that can be confusing. It can happen in female friendships. It even seems to be a high friendship goal to seem gay to each other haha ^^
Moreover, if I understood your message, this person is rather against what relates to homosexuality. Even if you think she could hide something, nothing proves the opposite for the moment. However, nothing prevents you from trying to approach the issue with her, but not directly at first. For example, say that there was little you saw a friend of yours who was lesbian, or something like that, and try to start a discussion from there to have her opinion.
And does she know that you are bisexual? Because in itself, if she knows it, that you are free and that she is interested and free, it is possible that she tries something. But I confess that just like that, I can't say much more. Maybe you can also try to ask to her friends or relatives if it's possible that she flirts with you, if she does that with others, etc. And if it is not possible between you (but I hope for you that it will be), stay with friends, and meet other pretty women ^^
Oh, and congratulations to you for getting out of this abusive marriage, you probably had to be very brave to get out of it. I wish you a lot of happiness after that :-)
Well, I hope that what I wrote will help you in one way or another.
