Thank you Nah. I usually don't post because I have nothing to add that hasn't already been said. I just wanted to add my perspective to Treasur's eloquent post.
I'd also like to add that it would have been easier had he passed. With passing there's closure. There is no closure with a vanisher. None. You know he is out there somewhere living his life. You wonder if he's happy. Will he ever regret his actions, apologize, contact. Heaven forbid you run into him (especially with her).
With death you don't feel like a failure, a freak, or judged because there are those in the world that believe you must have been a shrew of a woman for your H to have left you. They have no understanding of what a MLC is. They just believe you couldn't "keep your man".
With death you would feel free to engage in another relationship without thinking you are flawed or that this could possibly happen again (the cheating, lying, betrayal).
With death your free to recall and talk about the memories instead of wondering if your life together was all a lie.
With death you still keep those rose colored glasses on because now your view on life and relationships are a little more jaded.
This whole experience changes you as a person (and not all for good). So, yeah, death would have been MUCH easier.
