“You see the question is not "Can I ever trust him again"? but rather, "What contributed to this person's choice to betray me - why did they choose infidelity"? The first question is an unanswerable one as trusting your partner following an affair has more to do with YOU and how YOU choose to respond to being betrayed. The second question is much more interesting, and if answered correctly, more likely to keep you safe if you decide to heal and evolve together following an affair.”
