Hi,
I really hope you work things out with your wife. I started a poorly-titled thread about this kind of situation from my perspective as I found the hot-young girlfriend line quite amusing. I'm not even that young and only somewhat hot,
I just see paralells here.
I always encouraged him to get back together with his wife, to the point where I was actually telling him things he could do....try... say... but he has been so hurt by her affair, that he doesn't want her back anymore, though he's devistated. It would be best if they were back together, but she won't leave the new man, and now they are formally divorced. I think they're both just too proud. So don't let pride get in the way of getting back what you want, need and deserve.
I am glad you got your new job, it really does sound like an upswing for you. Try the open-ness, the positive thinking, the manifesting, and let your actions ride on the current of positive thought, and everything will work out.
