Need advice concerning EX, and..

Well i'm pretty much in the process of going back out with an ex...

Yes, "she's my ex for a reason"
Maybe i'm an idiot, and maybe deep down i know it possibly will lead to the same heartbreak and before, but i am into her and alwyas have been so much i just can't pass the oppotunity.

However, when we first hooked up, we didn't really do anything, and now 3 years on, we're back talking and flirty again.

However, i'm not sure what she's expecting out of me, and not sure what to expect from her, meaning, we're gunna' meet up, and not sure if she just wants my company for now, or jump straight into sex.

She's a year older than me and 23, what does a girl this age usually expect from a first date, she's a respectable girl, with a respectable job.? Don't know how to go about this, my first and only time was with my other EX, which took us 6 months to finally have sex.
