DH and I are living abroad in a country neither of us are natives of. My MIL (who is 70) told my DH she would like to come to stay. My DH and his family talk to each other on the phone when he is driving to and from work and they hardly ever contact me. DH mentioned a few vague dates to me - maybe Oct-Nov for a month. Today DH mentioned casually in a conversation on the phone that he was booking a flight for his mum to come from late Nov to Jan - so all of Dec and Christmas at least without discussing it. He did not book yet and did apologize. I thought about it and said can she come as close to Christmas as possible and more time in Jan as Dec is the busiest month of the year for me (we have 3 kids)? He is saying he wants to save money, Dec is more expensive and I am not being welcoming to his mum.
I think I should be involved in all the discussion ahead of time and decision making as I will be the one most affected by her stay. I am at home, DH is gone from 6am-6pm. AIBU?
