AITA for making my kid's teacher "collateral damage"?

Divorce may mark the end of a relationship, but the emotional fallout often lingers far beyond the final decree. For this father, the battle didn’t end when the papers were signed in January; it only intensified as he faced the harsh reality of co-parenting amidst bitterness and miscommunication. His ex-wife’s refusal to accept the fair terms of their separation has cast a shadow over their shared goal—a peaceful, supportive upbringing for their 7-year-old son, who remains blissfully unaware of the adult conflicts surrounding him.

When a breach of trust surfaced—his ex discussing their private drama with their son’s teacher without including him—he confronted the uncomfortable truth that the battle had seeped into their son’s classroom. Determined to protect his role as a parent and shield his child from unnecessary turmoil, he took a stand, demanding respect and transparency. In seeking justice not only for himself but for his son’s well-being, he found an ally in the principal, who recognized the toxicity of mixing personal grievances with professional responsibilities, underscoring the urgent need to keep their son’s environment free from adult conflicts.
