Not sure if there's any point addressing this, as it happened over a year ago, or if I would be overreacting. But I'm really upset and a bit angry too at this lie.
Before I met DH. His parents had separated and his dad decided to leave the house and fly to his home country for eight months.
I met DH and then a couple of years later, because of COVID, he invited me to move in with him and his mum. His mum agreed and said I could stay while we found a house.
Last year, both my mum and MIL came to see my baby when he was born. My MIL told my mum that I had invited myself to live with them, and that her husband was so upset about it he left the house. She basically said they had separated because of me. When it happened before I had even met any of them.
