AITA because I'll not defend my soon to be ex-wife in a post-nup proceeding?

Hey Guys,<br><br>Quick rundown, I married my highschool sweetheart. We were married for almost ten years, have 2 kids (6 and 3 yo) and she recently left me for my best friend. <br><br>I’ll not go into too many details in this post as it might have already happened but i’ll have our first talk with a lawyer tomorrow about divorce and my soon to be ex-wife's lawyer already reached out wanting a post-nup agreement in place. They are to this day in a relationship but she told me she started to date him 18 months ago. I don’t want to give you a full rundown of the assets we accumulated so far, we will most likely fight this in court instead of reaching an agreement but I'll sell the house and our vacation home nevertheless. <br><br>So the thing is, our ex-friends (her boyfriend's friends) posted online (facebook, reddit, etc.) and say that it was basically my fault that she cheated on me with him, because i didn't set a prenup and apparently didn't “protect” her and the kids. Now I don’t really care what other people say but both of our families and a few friends know some details. They also think i should at least leave our status quo and it would make my life easier as we wouldn't have to fight in court. <br><br>AITA if I insist on going to court and not leave our status quo but instead go for more in the post-nup agreement? Or should I just be the “good” guy and keep on the original plan with the selling of our house to ensure the kids get the money?
