AITA for rejecting the fat guy who wants to marry me immediately?

This guy I just met a month ago and talking already about fiance visa. I mean he got a cute face and I just broke up with my ex a month ago and Im still in pain and he's already talking about marriage and he's chubby too. And Im not into chubby guys aita for saying to him that Im into skinny guys? I was fat before and omg people are so mean to me and I dont wanna go back to my old self and date another chubby guy so AITA? Im not also into him
