The build up of stress and how your ex blamed the game for the relationship falling apart is what created the Block. It tied the game to a bad memory, It's good that you was able to get through it as very few people can once something bad in the real world gets attached to something we enjoy. Anyways keep at it, don't give up, and keep looking forward things may or may not get better but at least you will be mostly in control of your life and not someone else.
