Sorry you're struggling. It's a process, especially considering how long you two were together. You're going to have ups and downs. You got some excitement about talking to a new woman and then thought about those rose colored glasses, but when that high went away you came down and thought about the "what ifs" and ExW's new relationship. The key is to be trending positive over time. It can be tough to let go. It's natural to want things between ExW and her new guy to fail. Eventually if you can focus on enjoying your life you won't worry about that as much over time.
