Glad you returned to post an update. It doesn't matter if you have something exciting going on...we just want to know that you are okay.
I think it's wonderful that you are thinking about getting a keyboard. I think you will enjoy practicing and playing again. A great stress reliever too!
Well, your h may think that if he drags things out, you'll stop pushing for a divorce and separation of the assets, which includes the business, so he'll continue to toss out things that he knows you'll not agree to, therefore, he'll tie things up for quite some time. Your h is desperate to keep the business the way it is because he doesn't want to have to get a large loan to pay you off. To him that is more responsibility and accountability as well as stress to ensure the company stays a float. He's quite comfortable w/the way the company is operating right now and the income coming and expenses of what goes out. He doesn't want that boat rocked by any means.
You'll know more about where his head is at when he returns soon. Keep your duct tape handy as well as the STFU smoothies because he will more than likely get a bit miffed that you aren't backing down on what you want out of the business deal.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
