People who want a divorce are generally looking to date, whether they admit it or not. So you can look at it that way and get pissed at that, and then whether or not there is a current EA becomes irrelevant. If you can, don't give him a huge blow out unless you are REALLY done. The blow out will give him an excuse to get mad at you and BLAME you for his THROWING AWAY your relationship. I'm sorry you are going through this. I'd be bitter too at this point. It must be hard having waited for him while he is overseas. His behavior sucks.
