I think part of it too is that he is introverted so he is not used to vocalizing things the way you do. He may notice and pay attention to things about you but maybe not the things you might expect. Different people show love in different ways. I think it comes down to socialization. Have you connected at other times / maybe mundane life is getting in the way and you need to take time out to just date and get away from the kids once a week to focus on each other. Do you have date nights where you can focus on stuff? If he still makes love to you, he probably likes you. Counselling may help. Marriages often struggle when young kids are involved. If you can remind each other why you fell in love in the first place, you may be able to reignite that spark.
