回複：我快急哭了，請大家幫忙！

I feel very sympathetic to you and your hu*****and. I had bad experience getting into a difficult relationship with my PhD advisor. I was affected by that severely since my graduation: I couldn't get a postdoc job because I can't provide his recommendation letter to future employer. Just remember that your advisor will be very crucial for you to get your first job.
It was my nightmare for a year. I finally stood up again and found a postdoc job in another state. But I paid a high price- I have to be separated from my hu*****and.
But to make the best out of it, you can try to talk to the chair of the department and make sure he understands what happened. Sometimes, if you are lucky, he probably would like to offer you a recommendation letter. We call this situation "surrogate advisor". And if he likes, he can serve as your "surrogate advisor" until your open defense. Or another committee member will be nominated as "surrogate advisor" to guaranttee that you are fairly evaluated for your academic performance despite your relationship with your advisor.
Hope this help!
Good luck!
