Husband isn't acting excited, anyone else?

It's our baby #1 and 100% planned and my husband doesn't act excited. When I told him I was pregnant he didn't even get up to hug me, I was jumping up and down with excitement and when I asked why he acted like that he said "Well I expected you to get pregnant on the 1st try, so I'm not surprised." And then when I felt the baby kick for the first time at 16w I grabbed his hand and placed it on my belly. I thought it would be this beautiful moment, I was basically crying with joy and he had no reaction at all. I thought maybe he didn't feel anything but he did! He just didn't... show or communicate any emotion. The only time I saw him remotely act excited was at our ultrasound and he held my hand and smiled. At my 16w appt we heard the heartbeat and I looked over at him and he was looking at his phone (work stuff). We've been together for 10 years and I know he loves me... he just doesn't act or communicate it! It's breaking my heart. Last night we went to a party and he left me (an introvert) all alone. He kept walking away and talking to other people. When I talked to him abt it he said he didn't realize he was doing it. I'm so tired of this behavior. I'm so sad and hormonal and I feel alone.
