Husband question

So I'm not sure really why my husband asked me this. We have been trying since Jan and nothing is happening. So I guess it has given my husband time to think. He is starting to feel like maybe it's not meant to be or that he want be a good dad. He hasn't came and said those things, but he asked me the other night why do you want a baby so bad? Is it because everyone else has one. He didn't mean anything by it I think he was just curious. I told him it was because that was something that I wanted to share with him. Has anyone else experienced this with their husbands before.
