Most Helpful Guy
It sounds like, at some point in your relationship, prior to the divorce, he began drifting away and emotionally disconnecting from you. From what it sounds like, I'd wager he was the one who initiated the break-up, which means he had time to emotionally prepare himself to walk away. The problem is that, if there is no communication, or active effort to save the relationship, means you're blind-sided and left to deal on your own emotionally. It's a tough road to walk alone, so don't. Talk with your friends, or a therapist, and have them help you process your feelings and emotions. Talking can be the biggest help, as it gives you the outlet you need to release everything you have bottled up over the incident.
