" You mentioned that there are other people that use LM as a way to enjoy themselves. How can you do this? I mean have sex, but still being detached?"
Uh you're a guy right? Well imagine it's like you seeing a really attractive model. You know you could have sex with her on a merely physically level and not be attached emotionally.
In your situation, like everyone's suggested, your W is using sex to loosely hold onto you until her R with the other guy is more stable. Then she's going to dop you like a bad habit. Show her that you're more of a man than he is.
In fact, I would actually take custody of your son back especially when you know your W isn't at home when he is. Get your cajones back. Right now she's playing with them in her pocket. Show your son the man you want him to be.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
