Echo what has been said. Only do counselling if it's for a joint purpose. I.E. to either save the marriage or how to break up easily and co parent etc. I Don't think it's worth couple's counselling (from experience) if your both after different things.
Also, something I was not aware of. The problems have been there since 02 you say, wow, that is some long time. Have you taken a step back and asked yourself what you actually want anymore ? Is it your wife ? Is it just it's what you know ? Is it the fear of the unknown ? and is worth continuing to fight for your family worth what you may continue to go through ?
Lan - You know how much people respect you and your patience etc on this board and that we all think you are unbelievable, I just want you to now, after so long and so much effort, to really put yourself first. You deserve a happy life, you've tried your hardest so now, for me it's really time for your W to take some responsibility.
GL buddy and it's always your choice and nobody else's and we all will continue to support and respect whatever choices you make.
