<human>: Condense the text into a few key points

This is totally out of the blue. She's been acting perfectly normal and happy and then last night she dropped the bomb shell. The other guy is someone she met online and lives 3000 miles away (we are in NC, he is in CA). They have never physically met, but have been in contact for about a year and a half.

Today, she is leaving to stay with her mother. She says it's just for a couple of days so she can think, and that she doesn't have intentions of leaving me. She says that she does still love me but she's very conflicted at the moment and needs some time. We have a 3 year old son, and he went with her.

I am a complete mess. I didn't sleep last night, I've thrown up several times and the emotional pain is literally the worst thing I've ever experienced. I feel betrayed and completely lost. I have no idea what to do. I love her with everything that I am.
<bot>: Wife admitted she loves someone else. She left to stay with her mother "for a couple days." My world has been shattered.
