Getting told I need to lose weight

I've been with my boyfriend for a year and a half and have numerous time found folders of porn on him computer (that we share currently) and all the girls have a different body type than me. I was never really mad about the porn, but more thrown back as to how he was enjoying my body when all of these girls had a strikingly different body. I confronted him about it last night and he told me that he would love my body if I lost some weight, and I absolutely lost it. I'm all for woman's rights and empowerment so having someone say this to me just turned my eye sight to pure red. I spent the night at a friends house and came home to the computer password changed, all my things in bags, and constant messages from him saying "don't listen to the assholes out there." "Your body is perfect." I'm so confused, and hurt beyond belief. I've had problems with my body my whole life from the strict mold society puts on woman. I thought I knew him.
