lol it depends. Are you're friends smart when it comes to beauty?
If so then maybe it would seem the best thing to do is forget about her, but if your friend have no clue what they're are talking about and that others find her beautiful as well. Then you should trust your instincts are go for it.
She is cute. Who cares what your friends think. If we all thought the same people were attractive we would all like the same people. Sometimes you get to know someones personality and they become more attractive to you. In high school, maybe we cared what our friends thought. After high school...who cares. I have friends that have boyfriends / husbands that I would never date, but THEY see something in that person, and that is what matters...also matters to me that they are happy.
if you really like her you should..who cares what other people think
if you think she's beautiful tthen that's all it matters
