I am so very sorry SweetChiel that the situation has changed for the worse. You should be happy and not dealing with something like this!
It's one thing that he can't understand why you're upset, but to go to such extremes and send your stuff back and threaten to destroy the wedding certificate is unbelievable. He can't be totally indifferent to you and your feelings. If he does, then he doesn't deserve you! I'm sorry if I'm overstepping my bounds, but this is not a reaction you would expect from a person who loves you. A relationship can only work with mutual understanding, respect and compromise.
No matter what you decide or how it ends, please don't regret it. Don't measure your worth and happiness by this relationship! And you didn't let anyone down and it's not your fault! You did everything you could. (talked, made suggestions, made your opinion known, submitted to everything that was asked of you).
I know everything I/we say will not necessarily make you feel better. But know that I and the others are here for you and are happy to listen. Feel free to get in touch if you want.
And please don't feel bad about your progress with Bermuda. I know this is very important to you, but you know we are always patient. Take good care of yourself!
