<human>: Can you condense the text into three sentences or less?

Little bit of backstory: I [25m] got a job in another state expecting fiance [27m] to move with me as he had just finished grad school. He did not want to, keeping options open so he could get hired sooner. Got offered a job in a different state entirely many miles away. Shortly thereafter, fiance is lonely and starts looking for friends, comes across young guy [<18], is instantly attracted ("THAT is what I've been looking for), and realizes he doesn't want to work on our relationship and cheats on me. He was uncommunicative for a long period and eventually told me everything a few weeks later. We still talk as friends, but no lovey stuff and he ignores any attempts.

The problem: I still love him and want to work it out. He wants to pursue young guys for various reasons. He says he's not interested in reviving our relationship at all atm but isn't opposed to the idea eventually. He says he still loves me but I didn't have "that thing" he was looking for intially but grew on him over time. I did not see many issues in our relationship just thought we could use some help communicating issues. 

I am currently going to therapy for this but my question comes from this whole situation. Do I just keep being his friend and work on myself hoping he will find what he's looking for/comes back? Or do I look at the job opportunities in his area because a struggling LDR on top of breaking off a LTR just makes it that much harder to reconnect if not in person? He is very non emotional right now and needs time to process but I am struggling. I have talked about visiting him in a month or two which he is fine with as well. 

This has begun to affect my work and health and I am not capable of moving on because I am very attached to this man. I'm not really interested in moving on to a new person, I'm more looking for suggestions on how to better myself and the best approach to this situation. Thanks.

Just to clarify his opinion hasn't really changed about me, just that I'm not the 100% ideal person he was looking for at the moment.
<bot>: Fiance [27m] cheated on me [25m], wants to pursue younger guys 3 states away. I want to work it out, he is not ready for that but not opposed eventually. What do I do?
