Hi, I need some advice because I’m really anxious about something.

I’ve been talking to a guy long distance for a while now. Things are going well, we connect emotionally, and everything feels good between us. The problem is that he thinks I’m skinny, but I’m not. I’ve mostly sent face pictures and some photos that don’t really show my full body clearly. I didn’t intentionally try to deceive him, I just showed what I felt comfortable showing at the time. Recently, he somehow found my mom’s public Instagram because I follow her. She had a few photos posted from a trip to Barcelona that I was on. In one of the pictures, it’s my mom, my sisters, and me. It’s a full body photo taken from far away and I feel like I look really bad in it. My legs look big, my face looks swollen, and it’s just not flattering. He mentioned that he saw the pictures the dogs, my sisters, etc. and then asked me who the girl in the Barcelona photo was. I panicked and changed the topic because that girl is me. Now I don’t know if he suspects something, if he already knows, or if he was just asking casually. My biggest fear isn’t even just him knowing. It’s that everything feels good right now, and I’m scared that once he realizes I’m not as skinny as he thinks, he’ll reject me or say something hurtful. I feel like I’m just waiting for the moment where it all falls apart.I know if he rejected me respectfully I would eventually get over it, but the idea of him seeing me and choosing not to be with me because of my body really hurts. And we've been talking non stop on such a deep level he opened about some things so i feel so bad but im so embarrassed i just can't bring myself to tell him. I don’t know if I should tell him directly, wait and see what happens, or if I’m overthinking everything.

What would you do in this situation?
