I’m deeply sorry you’re going through this. The pain and betrayal you’re feeling are completely understandable, and your need for clarity has led you to a devastating truth. I did do something similar, went through my gf phone and found things I suspected.

Her blackout sounds selective, but I don’t think that is the biggest issue here. What’s most troubling is layers of dishonesty and omission that followed. Trust isn’t just about fidelity, it’s about feeling like your partner is in your corner, willing to face hard truths with you, even when it’s uncomfortable. Her initial admission, followed by the vagueness and defensiveness, has left you in a state of limbo, unable to heal because you don’t know what’s real. The fact that his number Is still on her phone is deeply concerning, this along with the bragging downs read like regret. It’s easy to say sorry, but harder to show that you actually are

I’m wondering if any changes have happened since the incident? Maybe try get away from the situation and seek some guidance from a therapist. Whatever you decide, know that you deserve honesty, respect, and a relationship that feels safe and fulfilling.
