A similar thing happened with me and my (long ago) ex. I loved her and her daughter, and the kid had nothing to do with the break-up. However, when I had pretty invasive surgery, my girlfriend did not come to the hospital with me or take care of me afterwards. She said her daughter needed her full-time and she could not take care of me. I suggested both her and her daughter staying with me at my house so she could look after both of us for just a day or two (the kid was very young). She said no because her daughter would be less comfortable at my house. So, instead, I had a friend drive me home and bring me necessities and then I just managed by myself. .
