How would you feel!!!!

So just found out gender through blood test! 13 weeks today.baby girl is healthy tested negative for the syndroms all three but here is the kicker your spouse was dead set on having a boy to carry on last name even though my brother in law has a son to do that already ... And was very touchy feely with your tummy and loving and everytime he calles you on break he would ask how are you doing ...i guess i am just afraid this will not happen anymore until he can figure out how to get over gender dissapointment...guess i just feel alone ....what would you ladies do or hpw would you react?
