Well, first thing, right out of the box......if she says she has a problem and dosen't ask for your help to fix it, that means she dosen't need you. Period.
People in love with each other, work these things out TOGETHER......or not at all.
My advice is, to cover your azz financially, do an emotional check on yourself and apply for every out of state tag you can possibly afford, just to take your mind off the (pain?) event.
Even if you patch it up this time, I would still take some precautionary steps. Sometimes people want to leave, but are not financially equipped, so they come back and postpone it for a while and rathole your cash.
Feel free to ignore my post, I have been married 4 times and have never let one hurt me, so I am no expert when it comes to the emotional part. But I've had friends and relatives who have been emotionally destroyed. My wife says I am "emotionally challenged"....I haven't cried since Old Yeller died.
In my case, when it STARTED getting ugly, I just walked away, signed over the house(s) in leiu of support, and started my life over.
They continue to reproduce, so you can probably find another one.
