Crap, just crap!

Things have been going along just fine, Jimmy C. and I have been doing well, he has been exhibiting exemplary behavior. 
Sunday I get a call from my girldfriend P.  She found out that K. is getting a divorce and just wanted that fact to be on my radar just in case something comes up.  I kind of figured a divorce was coming for K. based on the little bits of information that I had been able to put together.
So this morning, I find out that for the last week or two Jimmy C. has been talking to K. again.  I almost lost it.  We were getting ready for work and Jimmy C. asked me if I was ok, and I just said no and that I didn't want to talk about it then, we had just gotten our boys up and were getting them ready to go.  Jimmy C. called me after I dropped the boys off at daycare and was on my way to work.  He asked me what was wrong, and I told him flat out that I was debating on whether or not when he came home on Friday, to ask him to pack his stuff and go stay with his mom.  He got real quiet and said what, why.  I said because I know that you are talking to K. again.  He said it's probably not what you think.  I said, I don't care that she is getting an F'ing divorce and needs somebody.  WE AGREED that you wouldn't talk to her anymore and that you couldn't be her friend, period, paragraph.  He was very remorseful.  I ended up stopping by the Fire Station on my way to work to talk to him.  While I was there he sent K. a message that he couldn't talk to her anymore (this was at my request).  I told him I don't want to have to go and be ugly to K. I have no reason to believe she knows who I am at this point and we do live in a relatively small town we have one Target, one Wal-Mart, one Chick-fil-A (I have already run into her once in town).  I don't want her to know who I am, but I am seriously at my wits end.  She needs to find someone else to dump her problems on.  I know from my friend P. that K. has a sister who is divorced, so maybe she needs to talk to her, or a therapist...but damn, she can't have my husband! 
This is so hard!  Just when I think I've found my stable base again, it's pulled out from under me.
