Prior to your wife's loss weight, what was your wife's contribution to the marriage?
Specifically, you mentioned that she never was primary caregiver of your children, never cooked, never did laundry. You mentioned that since November 2015 she has been gone exercising/(sexting?/flirting?/planning-having meetups to run or more?) 95% of her waking time.
How did she spend her time prior to the exercise kick?
You mentioned that your wife's parents told you that you should treat her behavior as a sickness and you should let it continue because it will eventually pass.
Did her parents say anything to her?
In August she stopped sexting/pics with other guys. That seems to be the case. Was that in response to your being tough on her at that time?
She has pics still that she has hid, and a key like a PO Box. Have you ever found out about that key?
The whole thing about "get over it" and the stuff about she refuses to give up MFP and she even doesn't let you be a "friend" now the first teardrops ever about how you are on the verge of leaving her - part of that is your response - which was you for being a good husband who believes and wants his wife to be happy and thinking she wants the same thing as you do.
I want to consider a few things I remember or recently read or I just believe based on what I've seen here:
1. You caught her in February, she never took you serious, she never considered ending the compliments of other men.
2. In May, she had a consultation with an attorney. So she was ready to leave you, or she thought you might leave, and at that time she did not consider leaving MFP or compliments, she chose divorce over you at that time. I don't know if you knew about it in May, but in retrospect, that is my opinion.
3. She never let you be a friend on MFP, so that much is obvious that she still was keeping secrets, no other reason could be other than keep open unacceptable and inappropriate behaviors. Recently you found a message she said to other man (fake you) that they should lay low for a while, hubby was mad. To me it shows that she did not believe you would leave over that alone, and she can keep up with her cheating as long as she spaces it apart enough.
4. Now she has realized she miscalculated. So she offered you a crumb about letting you be a friend on MFP. With her plan, in my opinion, to give you a bone, like she has given you a few in the past, and this will be good enough for a while.
5. Now she is realizing the crumb of allowing "friend" on MFP is not enough. When she is served, she may go beserk at first but I believe she might then tell you she will remove herself from MFP. What will you do if that happens?
As for your youngest son, have you considered setting up a therapist? Some one he can talk to other than you and his mother. He is a smart kid, he will have conflicting emotions, and he may not want to express certain emotions to you for not wanting to hurt your feelings. And he will not get any help from your wife. Maybe you can call up his pediatrician and tell him/her what is going on and ask for a referral to someone he/she has used in the past with success for similar cases.
