AIBU to not want to invite husband to be's father's partner's daughter to our wedding which is abroad?
H2B's father and his partner have been together 5 years, not married and don't live together. His partner lives with her daughter.
The daughter is in her 30s and has a mild disability. This is not immediately obvious if you speak to her and she can be left alone for long periods of time (i.e. when the father and his partner go on holidays) and she does have a boyfriend of 3 years.
The clincher is whenever there are family get-togethers his father's partner always brings her daughter along. I think this is for social support as she has never felt accepted by the family. There has been a lot of coercive control and manipulative behaviour, which I suspect is the reason for her feeling that way.
Neither me nor my H2B are close to his father's partner or her daughter but of course the partner will be invited. However we don't want to invite the daughter.
AIBU?
