My ex said that I'm fat is it true

I'm 5'4 and my measurements are 34DD boobs 30 in waist and 41 inch butt/hips. I weigh 150 lbs. I feel fat because my ex told me that i am. He said no man will be attracted to a fatass like me.. I thought I was curvy but idk anymore because of that. I feel really bad now because I'm already depressed and insecure so this was the icing on top. I also have feelings for him still because he is my 9 week old daughter's dad and I love him. I really miss my old body 132lbs 34D boobs 26in waist and 38 in butt too. I really wish I never gained weight now...
