What is the likelihood that he will come back after a breakup?

Anonymous

He and I had a 4.5-year relationship that was mainly long-distance (3 hours away). We had usual issues throughout our time together. Around year 2 of the relationship, he said he wanted to break up since he felt like the "bad guy." I told him that we should go to couples counseling or he should go to individual therapy to figure that out. We decided to go to couple counseling, which was going fine until it ended early due to circumstances. After that, we were generally doing okay, & he bought an engagement ring for me. He wanted to wait until after I graduated from grad school to propose.

Over time, he stated that he was unsure of what he wanted from life and didn't know when he wanted to marry. I told him I wasn't in a rush and he could take as much time as needed. We decided to go on a trip together, and I made a small mistake by blaming him a little bit for a situation that had happened. He got agitated by it, calling me an as*hole, and held onto it even after the trip. The weird thing was that he told family/friends that everything was going great when he was so grumpy with me. By the end of the trip, he said he wanted to end it since that incident, for some reason, bothered him, even though I explained it myself. He said he would try individual therapy since he knows he needs it, and we agreed to continue the relationship until then. I met with him again a week after that, he was a little distant, but we chatted as if nothing had happened. Everything seemed to be going okay until a couple of weeks passed, and he said he wanted to leave again due to that trip incident still upsetting him. I had no choice but to let him go, and he has started therapy now and is enjoying it. We are doing no contact for a month, but his mom has been updating me about him saying he's taking this as a "learning experience" and that I'm a good person. But, he disclosed that he wanted to move to another state soon, and for some reason, they didn't want to inform me when he's leaving.
