that is very scary for sure. My mom had a brain tumor. I won't tell you her story, don't want to scare you. Just know that her surgery was scheduled to be 7 hours, they called us back to the hospital less than 2 hours later, the tumor FELL out of her head once the area was prepped. I will tell you from both a personal and a professional point of view, do your homework. Take notes in your dr appts, otherwise, you'll probably forget what the doc said that you wanted to look into some more. Get more than one opinion about your diagnosis. Be prepared for the worst and hope for the best.
I do hope your dh is feeling badly about his behavior now. I sure wouldn't wish this on anyone and I hope your marriage is strong enough to endure it. Please keep us updated. I'll pray for you.
Love
