What if my friend's ex and I like each other?

my friend still likes him. but I dont want to tell her I like him because im scared I would loose my friendship with her what do I do ?

I hate to brake it to you but your friend is going to have to live with the fact that you like her ex. after all that is her ex and not her current boyfriend they broke up for a reason either he or she dosnt want to be together anymore so I reackon you should go for it and your friend is going to have to live with it !
