Be patient, let him do his treatment & get leveled back out. Take this time to get your priorities set as to what you want life to be like when he does get home. Set your mind on what you will and won't be able to live with & stick to that. If the unacceptable behaviour starts up, that is the time to present your ultimatums, if it doesn't then even better. For now though, just chill some, enjoy this time that you don't have to worry about him & live on pins & needles with his behaviour. Worry about what happens when he gets home when he does.
"The struggles make you stronger, and the changes make you wise, and happiness has it's own way of taking it's sweet time.
Gary Allan- From "Life Ain't Always Beutiful"
