It's a NO for me especially after getting cheated on

Man Splits from Ex-Wife After She Cheats on Him. Now, She's Asking If He'll Care for Her Baby with New Husband in an Emergency
The man and his ex-wife also share a child together. After his ex-wife cheated on him, a man isn't sure he's in the wrong for not wanting to care for her child in an emergency. The man said his ex-wife's husband, whom she cheated on him with, was recently diagnosed with cancer. She asked if he'd care for their child if an emergency happened with her husband

The answer is too obvious as a "no." It's not even the revenge on the cheating; it's not his child,
not his responsibility . He doesn't love it. He doesn't have to love the child nor care for it.
