Re: wife moving out and I'm so hurt and confused
OP, I'm so sorry that you're here and you're going through this. I don't know if your wife is cheating or not, but I do know that if you cry, beg or chase her, you'll only push her further away.
One of you needs to step up and fight hard for this marriage, and it's not going to be your wife (she may have been trying for years but you were oblivious, happens all the time), so that leaves you.
Be a man - take charge of the situation. Don't ask her what's going to happen, TELL her. Tell her she has two options, 1: Stay and fight for the marriage, and then YOU organise how that plays out; OR 2: You both call it a day, she moves out and you start divorce proceedings (remembering that these can be stopped at any time), oh and she's not to take the kids.
