Self confidence

I’m going through a tough time right now in my relationship. My boyfriend is a lot skinnier than I am. I’ve been trying my hardest for months to lose weight and I only dropped like 7 pounds according to scale. I don’t see it. But I feel self conscious when we are intimate because I don’t have the best confidence and he’s so skinny and here I am over weight. It’s just bothering me a lot so I’m having trouble bringing my self to talk to him about this. We haven’t been intimate in close to a month because of it. 😩
