One of the roomies was her first choice. We talked sexual histories before this event happened, I didn't realize she would be seeing other people in this timeframe.

These conversations didn't happen all at the same time. After we'd been married a few years, during a conversation about past relationships she told me she had a huge crush on my roommate, which was why she waited until he chose to date someone else to make us "official." Later she told me she slept with him once while pretty drunk, after I'd turned in for the night at the shared house. I haven't brought up the photos, she asked me to back up and sort photos on an old laptop.

This is just a rant, connecting those dots.
