That's a shame, I've gone through similar situations too. But, hard times let you know who your true friends are. I've had friends I'd hang around with constantly and after a week or two of not seeing them it's like we're strangers, on the flip side I've had friends who I've gone years not seeing or talking with and as soon as we meet back up it's as if nothing changed.
Some relationships are easy to maintain and some can be so hard, some people like being involved in every aspect of someone's life to the point where there are no boundaries, and others would rather remain private. Each person is different and most people know not to push boundaries, the ones that do push boundaries though are good to find out how much you're willing to tolerate and how patient you are.
