<human>: I've been dating Josh for 2.5 years, and we've been best friends for maybe 6. It has always been long distance but recently (last year) became significantly less long distance to the point where we see each other multiple weekends in a month (usually 2).

I'm in school for a couple of more years and he doesn't want to move to my city, but I (independently of him) want to move to the city he lives in once im done with school and plan to do a summer internship there this year and spend parts of my final years in school there (we have to do co-ops in other cities).

This relationship has always been super easy and brings us both a lot of happiness but Josh has suddenly (literally out of the blue) said that he is missing having me around all the time and therefore thinks we should break up. I offered to spend more time in his city (very flexible school schedule, I could literally be there for a week at a time etc) and he feels that that will just make it more upsetting "when it doesn't work out."

Reddit, I know you can't make someone want to date you but literally the only problem according to him is that "he is risk averse and would rather avoid being sad and disappointed than be happy." This just sounds really self defeating and like a bad defense mechanism (if I'm playing armchair psychologist, likely picked up from a lifetime being raised by a single mom after dad abandoned them completely and after his previous serious gf dumped him for not being religious enough).

This is so, so upsetting to me. He's willing to talk about it but what could I possibly say to break him out of that logic?

Provide a brief overview of the text.
<bot>: Boyfriend wants to break up an otherwise ideal relationship because it will be LDR for a while and he's all "It won't work so we shouldn't try." Any ideas for diffusing bad logic?
