Seriously bro, if you want to do things that work, you're going to have to realize that most of what you have to do is counter-intuitive.
I get it, you're lovesick, broken inside, want your wife to love you again and you're torn up because she's with the OM.
She isn't attracted to you because you won't man up and it's time to reclaim those raisins you call balls and blow them up to watermelon proportions and to do this you have to start respecting yourself, she can't respect you now because you don't respect yourself - do you get this much yet? And she can't love you if she can't respect you.
I feel for you bobby, I can feel the hurt in your posts.
You need to turn this thing around, not to get your wife back but more importantly to get you back and when we get "YOU" back, the part about getting your wife will become easier & clearer.
The question is, are you ready to be really brave to face that fear and stand up for yourself for once in your life?
