Re: Looking for sincere advice to save my family
You need to put your ego aside.
Ask yourself how YOU contributed to the current situation. Like someone said above, your wife didn't just decide one day to up and leave. Something must have been going on (i.e. tension, fighting, etc.) from before.
You said, "To be honest I don’t have any value remain for my wife". One thing you need to seriously consider is that there are two children involved. Children, even babies, are extremely sensitive to their surroundings and can sense all the tension around them. If you have no value left for your wife (and perhaps vice versa), your kids will sense this, and if there is any fighting between you two, it will affect them.
