I'm glad you made it thru your trip to the in-laws. but I have to agree you have to let him have his space. I have tried your way and it really made things worse. I have let my H have some more room and tried not to ask 100 questions. I am trying to have alot more patience and I am trying to focus on something for me. What a difference in the way I feel and the way he acts. It is a small change on his part but it is a change. Once I quit obsessing over the OW ( not that those thoughts don't come back)but I really try to focus on anything I can thats positive.
I have been married 25 years so it is really hard to break old habits but it is a challenge. (IN my case you have to teach old dog new tricks). You have to have lots and lots of PATIENCE. I'm like you I want to fix things right now and get on with a happy life BUT we all know that isn't the way it is. We have to LEARN that there is some obstacles in life that we can't control and have to think our way thru and use our energy to better our selves and being impatient and negative won't help.
The feeling you have right now is almost intolerable but you can make it thru. I was just there last month and its amazing once I'm taking control of me instead of trying to control H how much better I feel. You can do it just put your mind and energy into it. Try not to make a big decision on your business till you are thinking clearly. It is alright to try and figure out different options but don't jump and do something that you will regret later. You must figure all options on your finances ( assets, debt, etc). You have to think what will be the best for you. Like Virginia told you Do you have plans on what you would do if you did sell? She has given you very good advice.
Hang in there. Think POSITIVE and Have lots of PATIENCE. These guys are giving you great advice. (Hey guys I posted feelin lost got any advice for me?)
We are all here to support you but You have to decide to make the change.
