Oh boy. Here's my take on this situation. Your wife sounds like she has her priorities out of order. Your child is the priority, or should be, for both of you, and not this business. Your wife dragged you into it, and honestly is being quite selfishly driven and obsessed. She cannot claim that you're being unsupportive since you've been helping her for a year! That's manipulative of her. Sorry, but I don't like the sounds of what your wife is doing to you. She claimed you would take a break over the holidays, and didn't. She went against her word, and you're naturally burnt out!

I would sit down and have an honest heart to heart conversation. Tell her that you're burnt out and that your child, not the business, comes first, along with needing quality time doing other life things. I would tell her that you need a break and that she needs to hire someone to help her. I would also advise that you speak with her about concerns regarding her priorities. Your child SHOUD COME FIRST.

If she cannot accept that you need a break and need to not be as involved, then maybe separation is the best option. Either that, or an objective third party couples counselor to help you figure out if separation is the best answer. If your wife won't budge and insists on keeping this pace up with you as involved as you have been, you may not have a choice but to walk away and separate.

I am sorry you are in this position. It's really not fair to you or your child.
