He Didn't Seem Into His Gf...

About a month and a half ago I went out to a bar for my birthday and there were bands playing...anyway there was the HOTTEST guy on the door...me and my girlfriend couldn't stop staring at him....he was ...beautiful! As the night went on he was joined by his Girlfriend....she was cute...and clearly his type...with tattoos all over her and a ring through her septum...she looked like  a bull...I don't know why she thinks thats attractive... Anyway....I ended up talking to her and well..she was really sweet but there didn't seem to be alot going on up there (in her brain) she was kind of...an airhead... I told her I moved over here from England and she was like...'oh...isn't that superrrr...' and kind of looked at me like I was speaking a foreign language. Anyway...I didn't think much of it...they weren't really all over each other...and then weirdly I met a guy there who I went on to date for a while...
HOWEVER the relationship fizzled out between me and this guy...and last weekend I went out with my friend to try and forget about this ex....and the hot guy was there....it turns out his name is Jack... (I love that name) he's the same age as me...he loves football (soccer)...we ended up talking for most of the night and when I bought up his gf...he didn't seem that interested in talking about her he merely said..'yeh she's a sweet girl' so maybe he knows she's an airhead too... He looked so shocked when I told him I didn't have any tattoos and wasn't into the Bully Bull look.... we ended up exchanging numbers... I txtd him the other night because we are all meant to be heading out this weekend to see a band... and well...he txtd back and was pretty flirty...I would NEVER take a girls guy... thats not like me at all... But as the weekend gets closer I am getting excited to seeing him....the most annoying thing is that he is totally gonna bring his girlfriend....But if he doesn't.....and he is really flirty with me.....what happens next?!?
