It was just a few months after I married their middle son. It was a big family get together at their house with ALL their family there (mine live in another state). We were passing around the wedding pictures, and I heard my MIL talking about how much her youngest son’s girlfriend had helped her prepare the house and food for the day (I had asked if I could help with anything, and she said no). Note: said girlfriend and youngest son treated each other horribly and had broken up and gotten back together several times already.
While I was standing there, watching everyone look at the wedding pictures, MIL said, “I always wondered what it would be like to have a daughter.” Hello? Here I am, your daughter-in-law, pregnant with your granddaughter. I had to leave the room.
We’ve been married five years now, and she and FIL are still treating me like a grandchild machine who’s going to run out on their son eventually.
