My fiance and I are having a huge disagreement about his sister. He lives over an hour away and his sister moved in with him in December with the understanding that she needed to be out before the wedding. I knew it would be an issue and told him that he should have given her a firm deadline. I told him that I did not want to start our marriage living with his sister. It is not healthy and I am marrying him, not his sister. She is not a go getter and often depends or lets others do things for her. She just graduated from college last May and has a steady and good paying job but no ambition.
My Fiance just told me that his sister is not moving out until after we get back from the honeymoon and will be living with us for awhile. I am livid. His sister decided there is only one apartment complex she wants to move into and its not available until after the wedding. His mother complained about him kicking her out on the street with no place to go. She has had almost 7 months to find a place and a family friend offered a room until her apartment was available. His sister has decided that she doesn't want to live there and move twice. She has been very inflexible about the situation and their mother is not helping either.
I am supposed to move my 1 bedroom condo into his house next month. If her things are not gone, I essentially have to move twice. I think the whole situation is wrong. His mother and sister should not be making decisions about my life with my future husband. Not only am I having to do lots of life changes (adjusting to married life, packing and moving, planning the wedding, finding a new job, etc.), but now they expect me to cater to his little sister who is a grown woman.
I have reached out to her by asking her to be a bridesmaid and tried to include her in things that involve the wedding (looking at invitations and lunches). I spoke with a therapist who said this is not a healthy way to begin a marriage. Am I being unreasonable by saying that she must be out and thats it?
