My boyfriend is suddenly paying attention to my belly?

So once I sent a photo of my belly and said my belly has become fatter and telling him an elderly offered a seat to me on the bus because he thought i was pregnant. He then pointed to a pregnant woman saying “this is what pregnant women look like” and I said “this is what a 7 months pregnant woman look like. What mine looks like is like a 2-3 months. (Of course in a jokey manner), And he asked “are you pregnant?” I said no.

So now after a few days, he scanned at my belly. And he joked “when I touch your belly I know it’s become bigger”
And later he asked me to let him touch it.
