I have been with my DP for nearly 20 years and we are getting married soon. It will be a small family affair and we decided quite recently after being engaged for a long time. My DP asked his DS (age 22) to be his best man and I asked our daughter to be my bridesmaid. Daughter very excited but I found out today that DSS is apparently less so.
He told DP today that he feels it would be wrong for him to be his best man and it would be disloyal to his mother. He says he has discussed it with his mother and she has no problem with it. Nobody in DP's family has asked him how he feels about it and it has dragged up a lot of pain for him about his father and mother splitting up. He lives with us and is unemployed and has never worked. He uses the house as a hotel and comes and go when he pleases. He ignores his half sis and openly tells his father he is jealous of her. I'm at the end of my tether and my DP is so sad after their conversation today. DSS is saying he may not attend the wedding at all. I really don't know what to do?
