<human>: So I've recently started dating (about six weeks ago) a lovely woman who is just finishing her first year of a three-year residency in internal medicine at a local hospital.

The good news is that everything is going pretty wonderfully so far -- we have great chemistry, she's very affectionate (in addition to super kind/smart/funny/pretty -- whole package), and we both genuinely enjoy (or at least, it seems like she enjoys) the time we spend together.

Of course, it's still super early with us -- we're only seven dates in at this point -- though things look promising.  The only problem is that, since she's still just in her intern year of residency, she works basically all the time (~80 hours/week).  This does not leave her with a lot of free personal time, and I have definitely appreciated that fact that she does make time to see me about one evening a week so far.

The only potential problem is that although for me one night a week is totally fine for a more casual relationship, I think this could have the potential to become something more serious, in which case I would want to see her ideally 2-3X a week.  Residency is the most challenging and demanding time in a doctor's career, so I know for a fact that this won't always or often be possible.

I don't know how to broach the topic that I would like to see her more often without it coming across as clingy/needy or even just putting her under more stress or obligation.  I work a 40 hr/week job so I can be pretty flexible with my time, but I'm looking for ideas of how to try to ask for more time with her without her feeling constrained or compelled.  

If this is the most time she can spare, it would be good to know, because it's likely things won't change much over the next couple of years (though intern year might be the most demanding in terms of sheer time).  

Ideas are appreciated.

Can you condense the text into a few key points?
<bot>: Just started dating a medical resident.  Want to spend more time with her, but residency sucks and she has limited free time.  How do I ask her for more time without her feeling obligated?
