<human>: I just broke up with my girlfriend of almost 4 years tonight.  We're both in college and have been dating since high school.  Overall very solid relationship, but in the past year or so it's been dragging.  Most of that is my fault (I have social anxiety problems and don't like socializing, where as she loves parties and stuff so I rarely do anything with her. This hasn't really been a problem until this year)

Anyway, she asked me a few weeks ago about what my plans were after college, to which my reply was essentially "I don't know, moving in with my parents until I can find a job".  Apparently this didn't sit well with her because she brought it up while breaking up with me.  She also mentioned she wanted to have an "adult relationship", but didn't really elaborate on this part. I still don't have any idea what thats even supposed to mean.  I'm not really worried about salvaging anything, I'm just confused.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girlfriend wants an "adult relationship".  Since we are both legally adults I have no idea how much more "adult" the relationship can get.
