Hi, grog. Welcome. I'm sorry to hear about your chronic migraines, and most especially about the strain it's causing in your marriage. While we wait for some of our married members to offer their perspective, I thought you might appreciate these articles about managing relationships and migraine:

I imagine your wife is under constant pressure as a nurse, especially this year. Have you ever seen a counselor? Counseling is an excellent resource for all kinds of situations, and it doesn't mean your marriage is in trouble. Even the healthiest marriage has room to improve and grow.
Please know that we are always here to listen and support you. We certainly understand how hard it is to be in constant pain and to feel disconnected from loved ones. Sending a hug your way! -Melissa, migraine.com team
