Tony,
I have travelled some very rough roads in my 10 years of marriage. If she's ever thought about making a move, i was unaware. What I do know is it's a constant challenge to have a good marriage. Here's the rub, both people have to work for it. The commitments you are willing to make, and then follow through on, must be met by her. I hope for the sake of all involved that things work out for the best.
