<human>: Can you give me the gist of the text in a nutshell?

I will try and keep this short.

Basically for the last 5 years my girlfriend has issues with communication and I always try to express my need of open and good communication inside of a relationship.  We try and work on it but it seems it gets better very slowly and only for a short while.

Now the issue is she at least once a month with make plans to go out with friends or work without me(not invited/no SO type outings) and will tell me she wont drink that much or stay out too late(like 10pm-11pm) but will stay out sometimes as late as 1am and drink more then she said she would.

Normally this would not be an issue if I at least got some sort of text or anything letting me know she will be out late so I didn't wait up or know I could have made plans for the whole night.

Should this be an issue?  It makes me feel unwanted and not cared for or thought of,  Am I just sensitive and overreacting?
