Does this seem odd or am I overreacting?

My husband and I bought a house a couple months ago. Recently things have been a little rocky and he has started referring things as "his" to our kids. Like he got pissy about a bunch of toys being on the couch instead of the playroom and he told the kids to get their toys off "his" couch. Then later the boys were rolling toy cars on the wall and he said "Stop putting cars on my walls." Nothing seems to be worded as ours anymore, just his. Am I thinking too much into this?
