The dilemma

You are staring at the tablet screen. The messages are from three weeks ago, sent to a contact saved only as a first name. Heart emojis, inside jokes, a message that says "I miss talking to you like this." Nothing that proves anything, but nothing that feels right either. Your sister calls from the next room: "Can you bring me the playlist? And tell me I look beautiful!" The ceremony is at 4pm. It is noon.

Your options

1. Go to your sister now and show her the messages. She should make this decision with full information.
2. Put the tablet down and say nothing. The messages are ambiguous, the timing is devastating, and you could ruin her life over a misreading.
3. Find the groom and confront him privately. Give him a chance to explain before you involve your sister.
