Sorry to hear of these problems.
It sounds like you really know what you did wrong and what needs to be changed. It's up to her if she wants to trust that you will change. Either way, spend as much time as you can with your son like others here have already said. I've been married almost 9 years and a father of 4 kids (2boy 2girls) 3 month, 2yr, 5yr and 7yr old. As for the computer I'm on and off it all the time between doing things with the family. I've had the computer in the livingroom for a longtime now so even when I'm on the computer I can still be apart of what's going on in the house.
