Husband said "move on"

While discussing how we felt after learning about a friends pregnancy, my husband said he "was sad". When I asked if he mean "was" or "am" he said "well...you gotta move on" in a matter of fact tone that didn't sit well with me. I know he was shaken by our miscarriage 5 weeks ago, but I don't get how he can "move on" so quickly. Is it just because he wasn't the one growing the baby and having all the symptoms and then the physical part of the miscarriage?  Or am I just not moving on quick enough???  I don't want it to become a fight between us two, and I don't think it will, it just struck me how quickly he can seemingly forget about what we just  went through.
