Whatever you have done has not worked or at least not yet. But more immediately you have a big change heading your way. Are you only seeing the downside of moving out? This moment is full of potential. It can be the start of you living the way you want to live. I am not downplaying the loss of your w and family BUT this can also be an opportunity to find yourself and grab your life between your hands and shape it to be great.
Like it or not you are about to separate. That is a sad fact. I am sorry but you can either wallow is what you haven't or thrive in what you have. Think of everything you can possibly do? Seize the opportunity to live.
You don't need to explain but I don't understand why you let her push you out. Why did you decide to give in? Secondly I don't understand why you are going on this trip together.
Are you on anti depressors?If not maybe you should reconsider.II feel you need help getting out under your despair.
Best wishes
