Monique, the former tease, has always been sure about her heterosexuality. She has been attracted to countless men and had quite a few relationships with them, albeit short lasting for the most part. So there's no way she could ever be attracted to, or fall in love with someone of the same sex. Right?
Well, here's the thing. The mind has ways of letting people know that sometimes life isn't so simple. One could be absolutely sure about who they are and what they want and be in complete disarray when that turns out to be false. Particularly if that shows as a desire that is stigmatized or relatively unknown. If so, the person will likely try to deny that they ever had those feelings, at least, they will at first.
