I feel it is a pretty normal feeling for the walk away spouse to have no responsibility or be somewhere with no responsibility. For me, my H left me with our S, which I would not have any other way, and did not see him or call to check up on him consistently and still doesn't, or pay any child support for the first 5 months. He finally started paying when he moved back in for 2 weeks.
It is important to stop focusing on him and to focus on you. The more you focus on you and you being happy, the more he will wonder and be drawn in.
