Guys how long does it usually take for them to leave her?

Okay a few new examples, instead of a song,:
My brother and his wife don't get along. Now neither of them has broken it off. They argue and fight, and really, it's not much of a relationship, or else my brother wouldn't stay at my house half of the time. Now he's a nice guy, he wants to give his wife some space, but the relationship between him and his wife has gone so far off course that when he speaks about it, it sounds like it's really hard to get it steered in the right direction again. So why doesn't he break it off, well, maybe he hasn't figured out if the "juice is worth the squeeze" I guess. There's a lot of conflict going on in his mind and he is very unsure of which path to take.

Now my best friend dates a lot and breaks things off with girls he doesn't feel right for him, pretty soon. But it also doesn't seem like he would extend the effort if a relationship didn't start on the right "foot" and even if the girl seemed great for him, but not at the present moment, because of whatever reason.

Now a persons dedication and timing plays a role along with conflict. How much dedication did they put in before the realization (of the person not being the one for them) sets in, and changes have to be made. Now those changes can be different for everyone. That's why you have people who will be together for reasons like "oh, I'm with so-and-so to see if we can work it out for the kids" or something like that. And people who will break it off a lot sooner without a certain level of dedication.

So in the end: So does he ramble, or do they ramble? It's a tough question.

I don't like feeling stuck or conflict, so I will break it off as soon as possible. I'm a nice guy so I'll break up with her and let her know the reasons why, but that I am resolute and I want to end it. I've never had a bad breakup.

I think it depends on how much they listen to led zepllin-babe I'm gonna leave you. I'm joking but I'm serious.

In the middle of the song, he says:

Baby, baby, I don't wanna leave you,
I ain't jokin' woman, I got to ramble.
Oh, yeah, baby, baby, I believin',
We really got to ramble.
I can hear it callin' me the way it used to do,
I can hear it callin' me back home!
Babe. I'm gonna leave you
Oh, baby, you know, I've really got to leave you
Oh I can hear it callin 'me
I said don't you hear it callin' me the way it used to do?
Ohhh
I know, I know
I know I never never never gonna leave your babe
But I got to go away from this place,
I've got to quit you, yeah
Ooh, baby.
Baby, ooh don't you hear it callin' me?
Woman, woman, I know, I know
It feels good to have you back again
And I know that one day baby, it's really gonna grow, yes it is.
We gonna go walkin' through the park every day.
Come what may, every day
Oooh, mama baby
I'm gonna leave you

Now in the song, the message goes back and forth, like he is trying to decide between his head and his heart. I mean he says "I got to Ramble" then he says "we got to ramble;" Could it be just a phase, or is it bad timing, what else could be going through his mind that causes conflict, until he finally makes the decision to stop his inner conflict, for what he sees as conflict, and start over or fix the problem at hand.

Depends on the circumstances... If they like the idea of being in a relationship then he'll take his time and most likely wait until the next girl. If they are sexually active then he is even more inclined to hang onto her until someone else comes along.

For me, I'd break it off within the next few (two?) days after realizing she is not the one.

Thats a hard one to answer - could be anywhere from a few hours to 20 years. Depends on the guy and his confidence level - I suspect that may be related to why girls sometimes dump a guy they are into but know he's not into them.

That's a VERY interesting question. Can't wait to see the answers you get!
