We have 3 little girls ages 6,4,1 1/2 and he wants to try once more for a boy.He actually said that the last time but this time he promises.I personally don't want anymore.However I don't want to disappoint him either.I asked what would happen if it was another girl,and he said then he would just have a lot of special ladies in his life but i really think it would disappoint him too much.I don't want to try anymore,but i don't know how to tell him because i don't want to ruin our marriage.any advice?
