I've heard of having a high maintenance partner, but never friends lol. Mind you, now that I think about it..... some people are just High Maintenance altogether! Maybe you just got unlucky and landed with several?
I have so many examples it's unreal!
I was really ill with flu last week, and my friends will not talk to me because I wasn't well enough to go out for one of their 18th birthdays. Like called me all sorts of names, selfish, a ****, etc etc...
And they expect me to be there at their beckoning call every minute!
