boyfriend called me fat?

Okay am I being sensitive or would you be upset? First of all - I'm "all belly" right now and not fat at all.... but my boyfriend just used the term "suuuuuuuuuper fat looking" to describe my body ..... I don't want to overreact but I feel like that's extremely rude and I don't even want to see him again.
We've been seeing each other like six months but I've been on the fence about staying with him since I'm having the baby next month and kind of just want to focus on me.
It seems to me he's just going to add more hurt and drama than I need in my life. Any pep talks welcome.
