I feel for you and while I don't know why your husband ignores you, I feel your pain. I hope the two of you can work things out, but that will require him to recognize there is a problem. If he is unwilling to try couple's counseling can you get a therapist of your own? Also, I think you should see your doctor and tell him about your vomiting and the reasons behind it. I'm concerned for your health and I hope you find peace of mind.
