<human>: Okay... this may be more of a battery of issues, but here goes:
I have been seeing this girl for just over two years.  We met in college, and we had a great time and grew a lot together during that time.  After finishing our bachelor's degrees, I went on to grad school about 4 hours away and she went back to her parents' house and is working.  We have been pretty serious for quite some time (had talks about marriage, family plans, life goals, etc.)

Since she has been back home, things have become more lame.  We can't see each other as much because we both have so much to do, which wouldn't be a problem except for the fact that at her parents' house, we never get time alone (not just for sex... her house is small, so a parent or sibling is virtually always present and it's hard to have deep open conversation).  She has been telling me that she doesn't want to come see me at my place because she's worried about her car lasting longer... Granted, it's a long trip, but that still feels somewhat bullshitty to me. 

 She also has begun to put on a significant amount of weight, and has stopped exercising.  It makes her less attractive (I don't consider myself shallow but I don't know how I'd handle dating someone I wasn't interested in sex with), but more importantly, it makes her less energetic.  We don't go out on walks or out for a drink or out to shows or anything when I see her now.  She also has begun to get more and more self conscious, which is a huge turnoff for me.

I don't want to just end it.  We've had a great, stable relationship for a long time, and even now we get along great and love and trust each other a lot.  I just could use some advice to help put some things back together, or to cope with these new aspects of her life.  

Thanks for reading.

<bot>: After I moved away, GF has gained weight and lost energy, and we neither do things nor have much time to ourselves when we do see each other.
