I give up

At this point, I am just going to throw in the towel.  I give up.  Another day, another bounced rent check.  I give up.  I feel like I've done everything I can do and nothing ever gets better.  He never changes.  If I'm not on my game 24/7 watching and monitoring what he's doing, things get out of control in no time flat.  I'm tired.  I don't want to have to keep track of a grown man's ATM charges.  I don't want to have to be the responsible one all the time.  I tired of always being the one who wants to work on the relationship or get our life back on track after it's been derailed by one of his bonehead moves.  There aren't enough apologies in the world to make up for the trust and respect that have been lost. 

I don't even know where to go from here.
