The same baby name for the same family

Candice
My boyfriend and I had told his family that we were expecting on Christmas. His brother broke the news that he had gotten his girlfriend pregnant also. Our expected due date is the day that their dad had passed away so we picked the name Daniel (their dads name) if we were to have a boy. Well we are having a boy and his name is Daniel. His brother found out the sex of their baby, they are having a boy and naming their son the same name as we are from first to middle (of course they will have the same last name) I'm totally pissed off at the fact but everyone else is ever so thrilled. I really want to change it but every time I bring it up my boyfriend and his family get up set and pissed off at me. What do I do?!
