UPDATE:

Went to W's apartment and got my forgiveness letter back, then things got heated. She hesitated at first, then went and got it. I told her she didn't deserve this letter right now because of A with OM and she replied, "I don't want it! I'm WITH (insert name) OM!"

Then something really effed up happened. My 13D came out of her room and completely attacked me for being selfish and defended her mom. 13D went on to tell me how much she likes OM and that mom is happy with him. Worse yet... I'm not a good father or husband because I'm not supporting mom's happiness with the A.

WTF?!?!?!?

And to add crazy to crazy... while trying to stand my ground with 13D over the issues without fighting with her (clearly brainwashed by W), during the lecture and attacks from my daughter, out of the corner of my eye I see my W standing there quietly nodding her head to 13D.

I explained that I do want her and mom to be happy, but I'm not going to stand here and support an affair even if we are separated with different residence and heading towards a divorce.

ALSO, why is the 13D arguing about the marriage? Not me as a father, but me as a separated H? When the hell did that become her fight???

Form of control, the 13D tells me to leave and get out. I try to talk to the W outside for 15 minutes trying to find common ground with our kids.

13D is hurt by me and loyal to W.

16D is hurt by W and loyal to me.

W was cold as ice and even tried to lie about things with A and OM that are facts. Trying to re-write the facts and details to suit her. CRAZY! She got snotty with me so I left...

Went home and talked with 16D (living with me) and she went off on W in a really nuclear text message to her. Wife copied me on it for parent support and I responded with I really don't care about your feelings anymore. Your problem with 16D! Also, since 13 is giving me crap and your hurting 16, we're moving out of the state at the end of the month and to just leave us alone!

No response from W.

OUTCOME: We blocked her and all her connections on Facebook. And 16 and 13 texted each other afterwards. Suddenly in the middle of the texting the tone got upbeat and mature. 16D knew W was on the other end; not 13D. "Hope your life gets better" and "This is probably for the best".

Sandi wasn't kidding when she said that this is not your wife or their mother. My W will currently destroy anyone or anything to get her "fix" again with the affair fog.

Now we go into the "witness protection program" for the next 6 months to let the dust settle and to work on our well being.

What a f#@%ing nightmare!!!!

I did mess up a bit, but didn't play doormat either. I got the letter back, didn't support the affair, blocked them from Facebook, and will be moving out of state soon. Simply working on establishing respect for me as a man and as a person. Not a total loss all things considering. Now for her to eventually miss 16D and possibly me with going completely dark.
