So ... what's the difference? 
Ultimatums are always presented as a bad thing in relationships. The general consensus seems to be that you should never give an ultimatum, because the person to whom it's given will call your bluff, and then there you'll be: single again.
However, I've been reading a book on boundaries in dating, and although it's been really helpful, a lot of their advice seems like ultimatums. You're supposed to say "The next time you _____ I will respond in this way: (insert consequence here.") And then follow through, of course. But really, what's the difference between that and an ultimatum?
Is it just a matter of wording, where an ultimatum would come right out and say what the boundary statement only implies: "If you don't do what I want you to do you will lose me?"
Is it the nature of the consequence, where an ultimatum leads to a breakup but a boundary consequence might be less dire?
Is it the acknowledgment that the other person's response to your statement is in their hands, not yours, and you're fully prepared to stand firm if they step over the line you've drawn in the sand? Maybe ultimatums are about trying to force someone to do something, and boundaries are about acknowledging you can't make anyone else do anything - you can only control how you respond to their behavior?
Is it the serious of the offense? Is it OK to make these statements for some problems and not others? And if so, what's the measuring stick?
Background: A couple of months ago I had to say to my boyfriend, "I cannot continue to date you seriously as long as (a particular situation) exists. When the situation changes, we can get serious again if you still want to." Even as I said it, I knew he might walk away, and I was fully prepared for that possibility. With my statement, I intended to set a boundary, but I'm sure what he heard was an ultimatum. He'd already told me how he responded to ultimatums, so I'm not at all surprised not to have heard from him since. I tried as hard as I could not to word it like an ultimatum, which would have said "If you don't fix this, I'm outa here." But he walked anyway - or, more accurately, chose not to fix the problem that I was choosing not to live with on a long term basis. I know I did the right thing, but I still have these moments of doubt ...
