I don't get it

Today I'm at a Mexican Restaurant, eating peacefully alone, when two women/girls walk in. Picture white trash, 22. Why did I listen in on their conversation? Because it was SO FREAKING LOUD! Truly, I had some difficulty understanding them at first, but once I put on my Luann Platter filter, I got it.

The gist of the story went like this:

Yee-eh-uh, Ah just about plum near deecided that ah just ain't puttin' up wid it no more.
Uh-huh
Ya know?
Uh-huh.
Well, ah mean, he ain't havin no thoughts about me or the kids not anytime. lahk yestuhday when I say, whatchu do wid duh tin dollahs I gives yew yestuhday? He say, I spent tit. I say, where. He say, at duh Jack in duh box. I say, you don spent the tin dollahs I gives yew on duh jack in duh box? how's me and your kid gonna eat when you be eatin out all the time?

[here I'm thinking, um, aren't you and luann #2 eating out right now? ]

I mean, I'm just talkin. and he gets all upset bc ahm talkin to some man with da kid in the other room. ah mean, she's sleepin. what am ah sposed to do?

At this point I left, but wtf?
