<human>: Can you give me a shortened version of the text?

Obviously, there are millions of variables. But it *does* work sometimes. 

My boyfriend (M29) and I (F29) were together for 11 months until last week. Our relationship was great, though rocky. We experienced probably 8 milestones in 7 months that most couples probably don't experience in 2 years. We both graduated with advanced degrees at the same time. We both needed to find the old' J-O-B in our field. I found one pretty quickly, but it is exhausting. He moved 3 or 4 times in 6 months (including living with me for 4) and is working a job that he is wayyyyyy overqualified for. He moved out really fast (as planned, but not discussed at the time of the decision), right when we were just starting to get the hang of living together. Then, we had to get the hang of NOT living together. Mostly, the problem was that we had to communicate a LOT in many different contexts and we just couldn't keep up. 

He broke it off because I was being (admittedly) really bitchy about things that I wasn't communicating well about. I own that and I *want* to change that. Now that I know that that behavior pattern exists, I know that that is something that I can change. Of course, it wasn't the only thing that could change in the relationship-we BOTH have lots of different places in which we can grow together. 

But: He said that most of his relationships last for a long time, and then end with the girl wanting more and him wanting out. When he has tried to get back together with them, it hasn't worked out (duh). Is that a fair piece of logic to translate directly to our relationship? In the process, together we identified several different things about our relationship that we wanted to see change and none of them are unreasonable or impossible. But he still thinks that getting back together isn't going to work. 

What do you think, Reddit? Is he being pessimistic? Or realistic?
<bot>: Boyfriend and I broke up after having communication issues from a million life events happening at once. I want to keep trying. He isn't so keen on it. What do you think?
