Mrs. 5150,
Thank you for the kind and thoughtful advice, the rest of you nutters are crazy!  No, seriously I value all of your advice.  My Dad always said, "There are only 2 mistakes you can make in life, choice of career and choice of a spouse.  Sometimes you get second chances in life, sometimes you don't but here's the whole story.

If I'm going to switch ways to identify without further confusing, A is my current GF and B is the other.

"A" knows the whole story between me and "B" from high school days.  "B" and I were best friends for 2 years with only the occasional sloppy, drunken kiss now and then.  But the girl is a bombshell and shows interest in me when I catch "B" drunken and snogging (kissing only) one of my friends and things between me and "B" get a bit chilly, if you know what I mean but we still see each other.  "B" is about to move away to school and she wants to f#$@ but I say NO because I'm with "A" then.

I find comfort in "A" and she knows the whole story and they know each other through me and it drives "A" insane when "B" is seen or mentioned.  I get the girl's wrath, if you know what I mean.  "A" picks up mail from my Dad's house which contain's a X-mas card from "B"....of course she's nosey and opens it.  What else does it say besides Merry X-mas?  Use your imagination but it got me a black eye, the X-mas of 1998.  I didn't write back to "B" but she moved on again and then a friend died 2 years ago and I was delegated to inform her.  

Still haven't called "B" but going to talk to "A" this weekend....again for the 2nd time but this time at a B&B.  "B's" birthday and my own is coming up in the next 2 weeks.

Hell, they are all crazy, you just find the level you can live with.

Very honest answer.
I see a problem with 'A' and domestic violence.
I see a problem with 'B' and her possibly wandering ways.
Sometimes sneaky is best...
Steel Rat's plan is pretty good, and not too sneaky.
Stay in control.  You may end up with someone out of the loop you're in.
If 'B' is ready to commit to you, and 'A' is prone to violence, get out and see what's in store for you.
Good luck.

If you are already in an abusive situation, leave before you find youself in a bad spot. Say things get to the point that you have to restrain her, guess who geos to jail when the cops show up?? I got a buddy you can ask about that one. As for the other, I went through pretty much the same thing about a year ago. Go for it, but take your time. Be sure of who she is now, cause she ain't your H.S. sweetheart anymore, that much I promise. The best friend is an interesting peice of this puzzle, unless there is an outstanding reason why not, she is definitely a possibility to look into as well. You know while we are finding out things. The only other thing to say is good luck!

Okay, some of you want to hear about the best friend.

I've known her since I was in 11th Grade in Germany going to a DODDS School.  Back then, 10 years ago she was my "very close friend."  Or for those who can't see between the lines...a F$*@ friend, for 2 years, while we saw others but were only close with each other.  We ended up finding others to be with and lost track of each other for a year when I moved back to Dallas with my parents she ended up in Denton, just a few miles away, the next year.  Since then, we've just been best friends, she's best friends with my GF too and before we got together actually experimented with each other, the details of which i still don't know today.

I guess I'm moving on up and moving on out.  It was simply bliss living with 2 women who walk around in panties and bras, and I'm going to miss the thong collection.

:(
