Self conscious

So I started talking to this guy on instagram, we've been talking every night (normal conversation) for about two weeks, course he does flirt, he says he loves my laugh and likes to just listen to me talk and calls me beautiful, & I find him so interesting and just so sweet. I haven't met him yet though and he keeps asking when we will. I feel ugly, and fat and do not like myself so much and feel like once we meet he would feel the same.... but I'm also worried that of I don't meet him soon hell wanna quit talking to me. Idk What To Do :/ I Wish I Had The Tiniest Bit Of Confidence.
