In my opinion if you are not attracted to her then maybe she is not the right girl for you. This doesn't make you shallow but when you love someone you find them attractive no matter what. My ex's who were in love with me didn't care when I didn't wear makeup or woke up after a heavy night with mascara down my face and bags under my eyes because they loved me and thought I was beautiful no matter what. Also when I look back on my ex who I was madly in love with I can see that he had some physical flaws such as being overweight but at the time I was still totally attracted to him because I loved him and thought he was beautiful and I thought his beer belly was adorable although to others i've spoken too it wasn't. Anyway what i'm saying is that in my opinion because of my personal experience I think that if you are not attracted to her the way she is then you may not be in love with her and there is probably someone else out there that would love her just the way she is. I'm not saying give up on her, maybe things will improve but she should not have to wear makeup to look attractive to you the attraction should be natural.
