Me and my partner have just moved house, 1 month into living in our new house and I get told that his mother (my mother-in-law) and his teenage sister is moving into our house as his mother & father are splitting up. I am ok with them moving to get themselves sorted and find a new place but she has the idea that she is staying with us until Christmas!? am I being unreasonable by telling my partner that I don't want them here for longer than 2 months, and that I don't want their cats here as I am allergic to them. I just don't feel like we could afford 2 other people living in our home, when I have a 2 month old baby and me being diagnosed with post-natal depression.
Am I in fact out of order for putting my foot down?
