Okay....great news that you went to the doctor and the edge is being taken off...
Yes I remember those days of dispair...I am a patient person now...remember NEW ME!...
Okay...if you feel comfortable with the finances being shared right now and you keep track to make sure he isn't shifting any money around...then fine, leave it....
As for his stuff in the house...I would just say leave it...makes it easier for him to feel like he has a "home" to return to...does that make sense?
I did keep all my H's things....when I moved I did box up things and put them in storage but other then that...I would just leave his stuff where it is (as long as it isn't in your way)
You do want to keep the road home smoothly paved....basically don't ASK him to make a decision on anything with YOU...travel, your personal business, your feelings, the OW, or anything about him personally....keep it all business....show him how strong you can be....and how independent you can be...show him you can/will change....that you will become the wife that he can discuss things with and not end up in a debate...
My H always let me have my way and I thought it was because he agreed or wanted me to have it that way...now he tells me it was because he didn't want the confrontation with me....but eventually this added to his internal unhappiness...this might be where your H is...he may not be able to verbalize this to you but in time with you NOT questioning everything he does...he will see a NEW YOU...one that he may want to be with...
As for the business...if/when he makes a FINAL decision with his life....i.e. he divorces you and truly moves on in his personal life without you....then you can make the final cut for yourself...if it doesn't happen then you haven't created a fuss about nothing...for now you are still his wife....still benefit from the financial part of the business....so let it be...it can always be dealt with later...not like you have to make that decision NOW...be PATIENT PATIENT PATIENT!!!
You CAN do this...your actions WILL change his reactions....YOU can have the power...YOU can make the difference!!!
