Feeling insecure

So I've been talking to this guy for a while. He's been wanting to meet up but I can't gather the courage to go thru with it. I'm very insecure about my weight. I feel ugly and fat and even tho he says he doesn't care about looks or body types I'm not convinced. I wish I could feel confident and beautiful bt I don't. I hate not being able to love my body or myself no matter how much I preach that to others girl I don't believe it for myself.
