when my husband say he loves me

When my husband says he loves me I used to be able to "feel it" if that makes sense. Now he tells me he loves me and I'm just like ok whatever. We have been married almost 3 years and just had a baby 1 week ago. It's like every since I went into labor and needed him and he wasn't there to help me I started to become petty af. Is this normal 10 days postpartum?
