The problem with that is that they've been there. She does take care of all of his needs, she has no problem doing it. She has no life outside of him. He's treating like a king with her. How does one give that up for real life? Real struggles?
Apparently she does not meet all his needs, as evidenced by this:
"He's called like 6 times since the email."
He is acting like a typical WS on the first day of Plan B: he is freaking out because he senses he has lost your propping up his affair.
And if she is able to meet all his needs, then you don't have a marriage anyway and are better off without him.
As far as I've been able to tell, the only needs I'm meeting are being arm candy, enjoying the same activities and taking care of health issues he's too embarrassed to show her. If I'm not meeting those anymore, I don't see how she'll have a problem meeting them.
Those are not emotional needs. And it is very unlikely she will meet the EN's you were meeting because she is a person who is very selfish and thoughtless.
Yes, I'm very very down right now, there is no light at the end of the tunnel. I feel like I just ended my marriage permanently.

You will feel better in about 2 weeks than you have in months and years. Just hang on!
He's called like 6 times since the email. #1 I spoke to him, #2 DS19 spoke to him, #3 DD8 spoke to him, 2 I ignored and the last was 6:30 and I was at work and he knows when I'm at work I can't take calls until my break. I didn't even see the call until I checked the time because my phone is on silent when I'm on the sales floor.
Are you deleting any voice mails he leaves?
I have another question, though. I don't call, text or email him, or see him but he's a friend on FB. Can I post stuff that he can interpret as I miss him or am I supposed to be making him think I don't need him at all?
No, delete him from your facebook entirely. Remember, you are in Plan B so he should get no messages whatsoever.
Do you have an intermediary?
