Finding out your boyfriend was involved with someone else can be heartbreaking. It’s natural to feel angry, confused, and disappointed. Your feelings matter, and you shouldn’t feel pressured to pretend everything is okay.
Ask him to tell you the truth about what happened. Was it cheating? Was your relationship exclusive at the time? Is he genuinely sorry, or is he making excuses? Honest answers are important if you’re trying to decide what comes next.
Only stay if trust can realistically be rebuilt and both of you are willing to put in the effort. If he keeps lying or doesn’t respect your feelings, it may be healthier to move on. You deserve someone who values your trust.
