R.D.
The average person changes 'best friends' every 7 years (that's a true statistic!)
I did recently try to reconnect with an old friend. We had had a falling out when she got married (because her husband hated me). Well, he left her, so she called me. WOW, HUGE MISTAKE trying to hang out. They're not legally divorced yet, but they're both living with their new BF/GF... she wasn't feeling well when we hung out, so I joked about her being pregnant... she took a test right then and there and WAS pregnant (omg!!), she had gained a ton of weight and wasn't taking care of her apartment, didn't have a car or a job, her kids were suspended from school for fighting (she has 4 kids!)... while I'm sitting here in the best shape I've ever been in, married with 3 kids, went to college, have a job, 2 cars, a house (we rent, but still), and my kids are all awesome.
It was seriously traumatic. We won't be hanging out again, I'm too old for that kind of drama in my life. She doesn't want help, just company, because misery loves company, and I'm not that girl.
