Even if she is the most good looking girl, I cant be with her just if she has ugly feet...is that normal ?!?

Whether or not it is normal for me is a moot point, it's normal for YOU. Everyone has certain things that attract them to someone else...sometimes it's facial hair, or bald men, or girls with blonde hair, or chubbier girls, or very thin girls...etc. Your *thing* happens to be feet. Although many people might find it odd, it's really no more stranger than women who have a thing for bald men, or men having a thing for women with big butts.
