In love with my best freind

ok here it is........

I am in love with my best freind but she doesnt know it I mean I go to her house like every weekend and play around and have fun and stuff and her mom even said that we would be perfect for each other but I dont know how to tell her.......any suggestions?

being too open sometimes isnt a great either, it might just scare her off and all, maybe she isnt looking for a relationship, its difficult, make sure whatever you do, is gonna be ok with her
