Missmyfamily, as difficult a decision it is to make, you CANNOT live the rest of your life miserable because someone else wants to emotionally abuse you. She is verbally abusing you as well. These are things people see most often in men towards females. You need to stand up on your two feet and let her know that you don't deserve to be treated this way. You don't have to say it in so many words, but two can play that game. Sometimes females lose interest because they don't feel important enough to the guy or they don't feel as though you find them as interesting as you did when you first met them. Your spouse sounds like she's trying her best to push you away and if that's what she wants then handle it. She may not think you would do it, show her wrong! I went through something similar and in the middle of my do it yourself divorce through a company that handles all the paperwork for you. http://www.divorce4her.com/testimonies.html.
They've really helped me to move on and soon have closer. GL
