sbh, welcome to the site. I am still struggling and you sound like you need one of the experts. so take my advise for what it is.
be happy whenever your around your wife. engage her in conversation, not relationship talk. become the man she fell in love with. dont tell her you want the marriage, show her. Focus on what you have done wrong and fix them. be there and supportive to her. Do not fight for any reason and make sure you validate her feelings.
if you are the direct type, then tell her how you feel. your feelings only. tell her that if you take the new job, it could be a new lease on your life together. it could be a fresh start. One that your willing to work on and give everything you have to make work.
My man, you know your wife, what is it that she isnt getting currently in the relationship? If you can figure that out, you will be on the right track.
