Should I be ok with my husbands ex-partner, who he has grandchildren with, staying in our home when bringing our grandson from another state, for a visit? We only get to see our grandkids when we travel to there homes that are out of state. My husband has had multiple affairs and recently confessed to a one night stand over 25 years ago with this ex-partner while married to me. I believe they have moved on but they have to have some relationship due to children and grandkids. Our grandsons mother can’t bring him and his father, my step son, passed away 5 years ago. We want to do what’s best for our 6 year old grandson, but I feel disrespected by he being ok with her staying at our house. Should I let her stay with us? Am I unreasonable? I feel this is the consequence to his bad choice.
