<human>: Can you summarize the given text in a few sentences?

I (22 M) broke up from a long-term relationship (5+ years) about a month ago.  For the sake of simplicitly we were basically married.  I recently hooked up with a girl that I think is really awesome and enjoy being with both inside and outside the bedroom.

We haven't spoken openly about it yet, but she seems interested in pursuing a relationship.  I say this because of the chain of events: relentless flirting last week, hook up Friday night, spend most of Saturday together, sleep together Saturday night, then she delayed me from leaving as much as she could Sunday morning.

This leaves me with a few problems.  First, I'm not 100% over my ex.  I'm pretty close, but I can't honestly say I'm completely over her.  Second, the new girl directly asked some questions about my previous relationship (eg how long was it, why did you break up, etc) to which I gave the vaguest answer that would satisfy.  Third, I'm not sure what *I* want out of this potential relationship.

Aside from general advice, I guess I'm looking for direct answers to the following questions:

* How do I deal with questions about my previous relationship?  The questions I've been asked so far have been about the relationship, rather than my ex.  She met my ex once, but I wouldn't say she really knows her.

* Is it a terrible idea to pursue a relationship while not completely over my ex?  It's not like I'm thinking about my ex all the time, but she still pops up in the back of my mind every now and then.

* Is she somehow trying to take advantage of me?  I don't know what she would be getting out of it as I haven't even bought her a drink.

My current strategy is to call her sometime tomorrow, arrange to meet over coffee or something in a day or two, then have an open and honest discussion about my situation.  I'll be pushing for either a slow-moving casual relationship, or a friendship that *\*ahem\** comes with a benefits package because, frankly, the sex is awesome :D
<bot>: recently ended a long term relationship, am on the rebound and found a little hottie that I'm not sure what to do with. HALP.
