Finding out the gender

Just some back story. My husband and I have an almost 3 year old daughter. We've been TTC for 2 years now. Suffered a few miscarriages. I'm currently 11 weeks. I got my results for my genetic screening and gender. Everything came back normal and great. We also found out we are having another little girl. I'm excited regardless. However I told my husband and his reaction was a bit disappointed. Which really set me off (maybe hormones are playing a role) He responded with "oh that's cool" I mean I know he really wanted a boy, but I feel his reaction is so uncalled for and rude. Especially with everything we've been through to have this second child. I feel he should be just grateful we are even given this opportunity. Am I wrong for being so mad at him? Or should I allow him time to get over it and prepare to be out numbered by girls? Please opinions seeing as I don't trust my own hormones.
