Unsure, you need to GAL. Read DR. Become a student of this stuff.
I will add a personal touch to this (which Pinhead may agree with) but your H is knee deep in an online game. This is pretty detrimental to a R. Since he is spending ALL of his free time playing his game, he's oblivous to his surroundings. Also, he's oblivious to what you are doing to win him back. He won't see it.
What he might see is that you're moving on, getting on with your life, with or without him. He's probably going to think you're moving on without him. As men, there is some primal instinct in all of us no matter how angry, upset, or apathetic we are - he's going to want to lay claim to you as a H possibly.
You can't make him feel that. He can only do that himself. But, if you want a chance at saving your M, you need to let him go COMPLETELY. You need to move on, do things for yourself, and he may or may not notice especially with his online activity. That's OK - you'll be better in the end regardless.
You're in a very crucial state right now. It is absolutely CRITICAL that you let him go now before any more damage is done. The sooner you let him go, the more chance you're going to have to save your M. Trust me, I wish I would have let go a whole lot sooner myself.
You'll be OK. You're strong despite what you feel right now. You're a good person for wanting to make this work. But, you can't make him feel anything.
