<human>: I'm 30M, I work a 8a-5p job and my girlfriend (who I live with for 1.5 year) works a 4:30p to 12a job.  Both of us are Mon-Fri workers.  She has made new friends and started to go out with these friends after work.  Which I am perfectly fine with, I encourage her to socialize with friends.  However one night she did not come home after going to a bar with a group of them.  I received a text at 2am telling me who's place she was going to and then a phone call from her at 7a telling me she wound up spending the night at "Joe's" house (he is in a gay relationship).  She advised me that she wasn't drunk and that everyone was just having such a good time she decided to crash there.  At first, I really didn't know what to think of it, I was just glad she was safe and I knew I would get a chance to process my thoughts on situation and talk to her later.  The more I thought about it the following hours the more it bothered me that she did that.  I thought it was kind of disrespectful in a way.  Not to mention, I don't want this to start to become the norm.  After all, I have to work in the morning.  

A couple days after this happened I calmly expressed to her that I did not like that she did that.  I then went on to tell her that she probably should learn how to control herself and know when it's time to go home.  I also threw in the fact that she's 30 and should have "grown" out of this.  I probably should have skipped saying that last part but why couldn't she just have called it a night after a few hours with her friends and come home?  I mean, we're supposed to be adults here... She started to cry and didn't understand why I took issue with what she did.  I reiterated that it was disrespectful and asked her to just not do it again.  She resisted and said she couldn't guarantee it wouldn't happen again.  Am I being unreasonable?  I can't help thinking the way that I do about this.

Provide a brief overview of the text.
<bot>: GF didn't come home after a night with friends.  She doesn't see an issue with it.  I do.  Am I being unreasonable?
