so i think i am in love with my best friend but the thing is she has a bf and i dont like him cuz he had cheated alot on his previous gf who is also one one of my friends and im afraid he will cheat on my best friend and if he does ill hurt him bad, cause i just mainly want her to be happy and shes happy with him, and i dont think she would be that happy with me, but i would hurt him if he broke her heart like her previous ex did
