The good thing of all is that you two have no kids together so nothing ties you guys down, honestly I would look for help like counseling or anything that would help you keep your mind of him you don't need a piece of trash like that! He treats you like crap and has no respect over you obviously he doesn't love you nor care for you or your feelings! Why should you?
I know it's hard but do you seriously want someone stepping all over you the rest of your life? And no you don't need another man at least not at this point in your life.
There is a saying that we can't choose who we fall in love with, which in your case is really too bad. But sometimes in life you HAVE to lead with your brain and not your heart. This is one of those times.
Time has a way of healing this wound, or at least letting it scar over enough so that you can go on. Give yourself a year to get over it. Keep putting one foot in front of the other, day after day, and after a while you'll probably realize you're living life again and not just waiting for it to end.
Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
