I’m not going to waste my time arguing with a man who’s lining up to be a hot lunch. — Jaws

There are some people you just can’t help.  No amount of love, tough or tender, is going to stop them from self-destructing and taking everyone around them along for the ride.  You can pay their bills, buy their food, heal their hurts, and they will continue to do stupid crap that sets the stage for the next episode of drama.

If you have someone like this in your life, you have to sit down and decide if it’s worth it.  Is the heartache, expense, time, and trouble worth what you’re achieving?  If it is, then, by all means, have at it.  If not, then at least you’re being honest about wasting your efforts if you decide to continue anyway.
