<human>: Can you summarize the given text in a few sentences?

I've been friends with her since we were 14/15, and I swear she has yet to grow up.  She's one of those girls that is breaking up with her boyfriend one week,  and getting back together the next week because everything's changed and we're so in love.  Anyways,  last week she wanted me to go somewhere with her and another friend but i wasn't up for it because I live on the other side of the city than them and where they wanted to go was another half hour drive out of the city from them.  Anyways,  she starts freaking out saying that she isn't going to invite me anywhere anymore because I never go so she is done inviting me places.  Okay?  I don't really care,  like I don't have time for these immature games.  Shape up or ship out.  So I haven't talked to her since the incident and she made a fb status today that said " baha best friends doesn't mean forever,  moving on"  so here she goes again on her little 16 year old freak-out again.  Do people ever really grow up?  This girl doesn't drive,  didn't graduate from high school.  I'm tired of being a chauffeur,  is it better if I just cut my losses?  She's been one of my best friends since I was 15, but life is hard enough without having people like that adding unnecessary problems.  What do you think reddit? I have a ton of really great friends who don't get mad over petty things.  And I'm going to try and start making new friends.
<bot>: friend since I was 15, acts like she is still 15 and is constantly freaking out over stupid things and making passive aggressive  Facebook statuses
