Should i tell my friend i like him?

I have just broke up with my boyfriend last week and im very very slowly trying to get over him , and i like my mate. I dont know if he feels the same buh some hints he gives me as though he does, although i dnt know whether to act on this or not as i dont want him to be a rebound and then i would loose him and hes my best friend... any ideas on what i should do? and please dont say tell him how u feel. :)
