W told me she is done & doesn't love me anymore.

If you you want a good book to read I recommend "The Four Agreements" by don Miguel Ruiz. It will change your perspective on everything you just posted. One of the four agreements is: Don't make assumptions. "Find the courage to ask questions and to express what you really want. Communicate with others as clearly as you can to avoid misunderstandings, sadness, and drama. With just this one agreement, you can completely transform your life."
"When she said "I don't know", she knew what she wanted to say, but wanted an opening for you to show you are the person she can still trust and talk freely to. "Its okay, you can talk to me about anything" is a good answer. I agree 100% to Mr. Bond, she will be in your life regardless, to quit so easily is not an option, you owe your child that much. "Normal" marriage, again I agree with Mr. Bond, there is no normal marriage. We look at society to judge what is normal, and that is wrong. Everyone is different, there is no normal in anything.
