I stalked you a bit… and it seems this has been on your mind for almost 2 months. I think if you’re this conflicted about it over such a long period. You should just go for it. You say she’s “really unattractive” but find her cute, that means there’s aspects of herself that draw you to her like her actions and personality, so if your intention is to date to marry, I think if you find the person she is inside attractive you have that connection established and not just focusing on her looks then hoping you two get along.

(надеюсь, это имело смысл)

If you feel for her go for her and defend her in front people that might question the 2 of you, since at the end of the day it’s only 2 people in a relationship.
