My heart goes out to you,Oh brother. You are indeed trialed. I will PM to you an excellent article on trials in the light of Islam. Please do read it and hopefully you will be comforted by it's contents as I am.
Meanwhile let not Shaitan deceive you into believing your marriage is in anyway a reason to your misfortune. Unless you are truly finding unhappiness and dissatisfaction in your marital life itself, don't assume your marriage is the bane to your life.
As for the one who oppressed and wronged you, again may he get what he deserves. Take solace in the fact that you are still better off than him, because you are not the one wronging another.
May Allah grant you ease soon..Aameen!
