Thank you for taking the time to help me think of ways to make this situation easier on me.
Just a thought comes to mind. If he were in a relationship with someone else, chances are, being who he is, he'd pretty much behave the same way as he has with you throughout your life together. So, the question becomes, even if you were to find ways to cope with your circumstances that made it "easier" on you, why would you want to be in a relationship with this kind of man?
