How do i tell him i like him without it being awkward?

well first be there for him since he just broke up with his gf. he might still have strong feelings for her. Because you dont want him to use you as a rebound. but he doesnt seem so upset about his now ex gf you can like just talk to him and tell him. it doesnt have to be real awkward if you two are good friends. just be honest with him and everything she work out.
