I'm sorry, it's a vile betrayal, that's why in the last two months, according to you, they were the worst, if she is fucking her partner, maybe since when, maybe neither of them are your children, for a woman to have such a degree of hypocrisy, being dazed, is that he has no love for you, and perhaps his partner does not want to take care of the son, and you have to smell the plan that you are, that's why now he wants to go to counseling, if what he said was true she tells you, why didn't she ask to go before, to MC,
She tries to blame you, so that you accept the blame and she is free of everything,
Your wife is disgusting, really, having a little girl at home, and according to her, since November fucking another guy and being pregnant, not caring about getting an infection, and at Christmas,
You should do much more under the carpet, this is very turbid, the distance, it was for her, fucking and giving love to the other guy, maybe they are still going and she is just waiting for him to want to recognize his son to leave you later,
Start working on yourself, with the degree of hypocrisy, lack of respect, and zero dignity of your wife, you can expect anything,
AA and you still haven't told MC that she attends a therapist alone, that if she wants to work on the couple, which I doubt, that she bring her first, to find out, how she could get to such cruelty,
I repeat, work on yourself first, and prepare for the worst, you may only know 1% of the real story. and really she stops blaming you, nothing justifies what this woman did.
