Rev,
I am so terribly sorry that you've been treated so horribly.

It's understandable that you're feeling down, but please don't make matters worse by becoming your own enemy. We all have a tendency to behave this way. When you think about your situation be careful not to overdramatize it in your language. You are not a loser. Why are you talking about yourself that way?

I think that you should accept the fact that you are a very capable, worthwhile human being who is experiencing a terrible, and unexpected, loss. Treat yourself like a king. Don't let one more personal insult enter your head much less leave your lips. Don't isolate yourself. Get out and surround yourself with good people. Most of all, don't punish yourself for feeling bad and talking about what is happening to you.
Now for your wife's denial of her previous feelings for you. It's certainly hard to ignore, let's analyze it a bit. There are two possibilities relative to this admission. First, she's telling the truth. In that case, she's fixing a very selfish mistake that she made early enough (35) for you to heal yourself and move on. If she's telling the truth than she was wasting your years away with her when you could've been spending them with someone worthwhile. How could she be so arrogant to think that she wasn't wasting your time? I'll never understand how people can delude themselves this way. She's not better than you. She wasn't doing you a favor by blessing you with her presence.

The reality is that there is something really wrong with
her. Why would she marry someone she doesn't love? This doesn't sound to me like someone who is capable of having a lifelong, loving relationship. Thank goodness you finally found all of this out.
The second possibility is that she's lying. If so, does it really make any difference? She's still leaving. The only difference it makes is that now she's being hateful on her way out the door. What kind of woman would be so cruel? Surely you deserve better than someone who behaves so destructively. At least now you can move on to someone who will appreciate you.
Now you've been through two bad relationships (marriages). I think that you really need to start taking care of yourself. You need to spend at least a year (or two) developing your own interests and learning what makes
you happy. Take some classes at the local college, take up a new hobby, do something different. Just don't jump into another relationship. You're suffering from a low self-image right now. You're the only one who can heal yourself. A new woman at this point in time will just take you down the same path you're on right now. Healthy people attract healthy people. Heal thyself.

You're in my prayers.
