<human>: Can you succinctly summarize the text in 1-3 sentences?

My wife, Jane, and I have been married for 4 years now. We have been - and are - very happy with each other. I was a little naive as far as relationships were concerned when we first started dating, while Jane had had a relationship before she met me that was abusive. During this time, she met some friends online who she became very close to. She is still very close to them, and texts them everyday. One of them in particular is her best friend and very close to her.

I wasn't concerned about this, but I had a niggling doubt at the back of my mind that wouldn't quiet down, and I admit I erred and snooped through her messages. Most of her messages seemed to be her reaching out for some emotional support; the kind of support she always said I gave her. So it baffled me I saw her (what seemed to me) fishing for compliments from him. I also saw several messages where he was blatantly flirting with her; to give her credit, she would always reply "I don't know how to respond to that" and shut down, and the next message would usually be from him apologizing. But it bugged me that she never told him to stop doing it outright.

I was really bothered by it all day, and I confronted my wife after I came back home. She was angry that I snooped, even angrier that I didn't trust her, and told me that he was engaged to his long-term girlfriend and that he and his fiancee were happy together, that she considered cheating to be a dealbreaker for a relationship and would never, ever consider doing it, that she knew what an emotional affair was and that she was not involved in one. she told me he was her best friend and she had always confided in him when she was down, and I had no right to question that.

So it's now 2 in the morning and I'm sleeping on the couch. Am I paranoid for thinking my wife may be having an emotional affair, or are her actions normal? I don't mind grovelling if I'm in the wrong, but...if I'm right, I need to know too, right?
<bot>: Wife has a best friend who she seems to rely too much on for emotional support; he also keeps hitting on her now and then and she won't flat out tel him to stop. Is she emotionally cheating on me?
