I have had the "light on" without anger or judgement for a long time now. I don't even say ''hi'' unless he shows a willingness to be friendly first. I see that he enjoys the availability of our home, like he needs to know there is a constant he can rely on.
He comes in, I go about my business, he sometimes says hi or waves, I leave him alone. But, here's the but, he has thrown it in my face, saying that he is getting away with everything.
He has even gone as far as saying maybe he should push it since nobody can stop him. My repose to that months ago was for him not to read my silence as weakness, he agreed out loud. He said at times he's scared of me.
My S21 wants to break "the light and put up a pad lock" luckily he's reasonable in the end.
The "good feel" he gets about coming home then ends...and in come the beginning of his anger, the dep that makes him want to leave, because he's only dep here you know!
For now the light stays on....
The past can't be ahead of you in the future. You don't have to figure it all out, just pick a direction. What's next...I don't know but I can't wait!
