Oh no, that's awful... I can't believe he would go to such an extreme so quickly. I'm so sorry. :( I know I don't know him and so this might not be fair to say, but it really seems like he just expects you to fall in line with his way of life. That's not a marriage, not a partnership. That's controlling another person.
Don't blame yourself and don't take on the disappointment you are worried others might feel about this situation. You've already done everything you can to work things out. You've made so many compromises for your marriage. You cannot help that he is unwilling to do the same. Just because you married him does not mean that you have to suffer in a situation that is so one-sided and mentally unhealthy. You expected to enter into a partnership when you married him, and that is not what he is giving you.
I don't know what will happen next, but please don't compromise one more thing for someone who isn't willing to do the same for you. I realize you don't want to give up yet (of course you don't, he is your husband), but if he is willing to so easily give you up, isn't going to put any real effort into resolving things with you, is going to always prioritize his mother over his wife, then as you said...how is he your husband?
Please don't worry about us and Bermuda. We could never be disappointed with you. We know you love this project and will always fight for it, but right now you have to take care of your own health. You are going through so much right now. It's completely understandable that you need some time to process everything and deal with it all. You are a bright, sweet, talented, kind, creative, beautiful person, and I really hope you will be able to find a way forward that makes you happy!
