@winushka,
Yes, that is so strange an unacceptable that one would find a person attractive that has the bad graces on not fitting into some mould that you and/or society deems acceptable.
You need to immediately distance yourself from this person, and find someone that you can pigeon hole into your limited understanding of human relationships.
Seriously, do this woman a favor and don't force her to find out on her own in the future what a shallow idgit you are.
Has it occured to you she might not be attracted to you in any way? If she's lovely with a great personality she deserves much better.
