So I married Alice and after another two seasons, upgraded the house to include two bedrooms. I have Alice at max hearts, and I give her gifts every day, but it's been two seasons since I've upgraded the house to have room for kids, but she still doesn't ask.
So, while I was waiting to upgrade the house, I give Nina a locket to see if the game would let me, and it did. So now, I have Alice as a wife and Nina as a girlfriend. Did I screw up by doing this?
Every once in awhile, Alice will come out with the dialogue that she feels like we are drifting apart.
