TITLE: (M-33) Big guy gets asked out by (F-29) hot girl for drinks - Kinda of freaking out here...
POST: So I ended up getting a to know a girl (29) from Tinder (no clue how this thing works) and after about a week of texting back and forth she asked me out for drinks. I find out she's actually friends with my old neighbor and I went and checked out her facebook page and she's really hot.
My problem is, I'm 4 years older (33), and I'm a bigger guy - 6'3' and about 280 and I'm afraid that when she sees me she will just freak out and leave. 

On top of that, she knows and possibly dated another friend of mine when she was out of state at college years ago and I don't know if I should bring it up. I don't want to ask my buddy for fear of getting too much information or if she was just a fling.
TL;DR: 
I've got asked out for drinks with a hot girl and I'm self conscience about my size. I know she knows mutual friends but I don't know how those relationships are truly valid.
