you're not wrong in general, but in this specific post, i'm really questioning the way the wife handled things.

those are the actions of a) someone who has very good reason to suspect OP and/or be insecure in the relationship or b) someone who is cheating/lying and trying to cover their own behavior and guilt. so if OP is omitting something, my guess would be it's something really big that sort of invalidates his whole post, like prior infidelity, problems in the relationship, etc. my point is that there aren't many minor details that could be omitted that would also explain the wife's behavior.

also, out of town for a bachelorette party? maybe the wife did something she regrets and that's what started this whole thing. so my guess is that OP is intentionally lying, or there's more going on with his wife.
