I guess you could say it just like you've described it here.
Just be straight with him tell him things are not working, I'm sure he knows it's coming at some point
Good luck, hopefully you kick him to the curb and go have some fun
just be honest and calm with your words
Best of luck telling him how it is ....
start with a letter. maybe even throw it away after writing it. But get all your thoughts out in a row. Make a plan to meet and talk. Let it out. But keep the extra mean things out. In the end say you and he can not live together any longer. Stick to it and don't talk to him for a few weeks. Good luck
Well you would be best not to put it that way, since its "You go or you go". Maybe tackling it from what you want for you and how different that is to what he wants. If he cant win, which seems to be the case, presenting it as an either or situation isn't appropriate
Wow good luck
