A little highschool-esque i will admit, but i really do need help!?

so recently i was put into a situation where i am now forced to choose between 2 people that i have feelings for. Person 'A' and i have had a "closer than friends" relationship and has waited for me when I was in past relationshiips. Person B is a relatively newer close friendship and I am not sure if Person B has feelings for me yet, but believe there is a strong possibility of something happening. As shallow as this may seem, I would pick 'B' anyday for looks, yet both A and B are very compionate. Is it worth risking everything I had with 'A' to try having a relationship with 'B', knowing that things may not go well? Please help!!!
