I need help ASAP!

I feel like I don't look good enough for my man. Especially since my mom said I looked fat a week ago. I've been having trouble not thinking about my weight and if I look okay. I'm not a sappy kinda girl and that's why I can't tell him. Cause he will get really sappy and cheesy on me. We've been dating for 8 months now but we wanted to be together way before then just wanted to wait for school to get out of the question. He got me a promise ring the day after I graduated high school. ( He graduated the year before me.)... Idk. I just want him to just look at me and tell me what he sees. But I want the truth not the lovey dovey stuff because we're together. I dont have many body pictures never liked the way the camera showed my body. You know? Sorry for this confusing post. Just needed someone to hear my thoughts.
