Future father in law

NSR

My bf and I have been together for over two years now. His dad is constantly making comments to m about my weight. I weight 125 and I’m 5’3 so I have a normal BMI and weight. Well the other day I left to go to Dollar general because I really wanted to Reese cups. On my way out of the house he says “you need to stop eating all this junk food it’s gonna catch up to you” and I told him “how about you worry about you and I’ll worry about me”

But my feelings were really hurt about it. I keep thinking about it and it’s made me very insecure about my body
