AITA for refusing to save my marriage after my wife announced she's pregnant?

At our anniversary dinner, my wife announced she was pregnant. 2 nights earlier, I'd confronted her about kissing another man outside a hotel. When she reached for my hand, I pulled back. Her mother frowned and said, "Hold on. You told me he'd already agreed to everything." ---------------🦖D - Stories🦖--------------- #reddit #stories #redditstories
