Dating guys when you are fat

I have only dated women, but I have always felt like I’d really like to be with a dude. So I tried for 5 months. I met so many guys that were interested in me, but would immediately lose interest when they saw me in person. I have a very expensive membership to a dating site, that has a lot of successful guys on it. I had a very complete profile, and was pretty good at messaging guys back. I’d message them, talk for a bit, they would ask me out, we’d meet up, and they would never speak to me again. This happened a dozen times. I’d message them afterwards and ask what was wrong, and they’d say I wasn’t their type. I know that I’m fat, and I’m not delusional, but I also know that I’m very cute. I’m surprised that people care so much about being in shape. I don’t know how you date someone when you look like an underwear model. No matter how hard I try, I can’t get in shape, I just can’t. I have been fat my entire life. I’ve been on diets that work for a while, but I always gain the weight back. I’m just a fat girl, and I’m okay with it. I’m not really sure I want to date anymore. I’m so frustrated. I tried so many dating apps and websites, and had the same problem across all of them. I’m surprised that I can’t just find one guy who is okay with my weight. I feel so alone.
