I have this guy friend whom I really like but as a friend , and he asked me out on a date
I don't want to say no to his face and ruin the friendship that we have but I also don't like him that way in order to accept the date invitation (I have a crush on another guy tbh)
Saying "I like you as a friend and no" will ruin the friendship I have seen this happening 
Did anyone go through this and can give advice?
