Wow, this is such a heavy situation—I can't imagine how tangled your emotions must be right now. On one hand, there's this urge to 'even the score,' especially after the betrayal you've endured. But I’ve seen friends go down that path, and it rarely brings the closure they hope for. Instead, it often layers more guilt or chaos onto an already painful dynamic. Maybe ask yourself: Is this lover about filling a void, or genuine connection? And more importantly, what do you want from your marriage now? Reconciliation? Freedom? Those answers might guide you better than impulse.
Confessing could force a raw conversation about the state of things, but it might also nuke any chance of rebuilding trust. If you’re leaning toward honesty, maybe test the waters with a therapist or neutral mediator first. Personally, I’d prioritize figuring out my own needs before dropping another bomb—because once that truth is out, there’s no taking it back. Sending you strength; this stuff isn’t black-and-white.
