It sounds like you have set a boundary. Usually setting boundaries are easy; it is sticking to them that is difficult.
I hope the time with your sister is healing, joyful and marvelous.
Hi Bekind, thanks so much for this. In answer to your question, no, I don't have the right to kick him out, unless he is violent (which he is not). We lease a place together (though I pay all the rent, and have done since the beginning) so changing the locks isn't an option either (and of course I wouldn't especially have the right to do that, either, except perhaps morally!) I have restated, in texts, that I need him to leave. My leaving is theoretically possible but I strongly feel that as I pay the rent, and need a stable base to go to work so I can continue to pay the rent, that he should be the one to go.
As for enforcing the boundary, it's so bloody hard. I'm avoiding speaking to him because I think I'll cave if I do. I'm far from joyful right now, but I am getting a lot of love and support from my sister and brother in law.
