Ok Guys, please give me insight.

Let me start by saying, my husband is WONDERFUL. He really is the greatest. We have two beautiful boys. Our first is four and our second is two. All we can talk about lately is trying for another. Soo, I downloaded this app, to help me track when I ovulate and such, and I let him know when I am, and we will have sex, but he never finishes inside me... Like tonight he literally stopped right before he finished and said “Babe, I think we should wait a little longer before we have another one” Which I understand if that’s the case but why is he telling me he wants another baby, if he doesn’t? I willingly have sex whenever he’s up for it, so he’s not saying it to get me in bed or anything like that, but it really hurt my feelings because I want another baby so bad since we started talking about it...
