Those things are much (MUCH) easier if you provide feedback on things you don't like instantly. He didn't commit something -- tell him. He did something in the way you don't find the best -- tell him. You think he's slow -- tell him right after you found out. After a while if you decide that it won't work for both of you and things aren't improving, there should be already a good hint for the guy by that moment. If you just hold everything without sharing with him, for sure that would be very hard to tell him your concerns. Like apple. Way too hard to simply swallow. But it's ok to go bite after bite.
