<human>: I started dating this guy - basically the man of my dreams and things have been going well so far - ~3 months. Last night we had a disagreement and is basically telling me that he doesn't think exes are appropriate friends. I can't say that I'm friends with ALL my exes... but one of my exes, who I dated throughout HIGH SCHOOL (more than 10 years ago) is and will always will be a very close friend of mine. He and I don't talk very often by any means, maybe a few times a year, and he lives more than three hours away. But we do have one of those friendships / relationships where we don't have to talk everyday or every week, but when we do see each other, it's as if no time has passed at all. There is nothing inappropriate about my friendship with my high school ex-boyfriend - he's in a serious relationship and so am I. But I'm not willing to cut ties with my close friend over my new relationship. Is there a way to explain to my new boyfriend that I'm not going to choose between them?

Summarize the given text in a few sentences.
<bot>: My new boyfriend is not okay with me still remaining friends with my high school ex-bf from 10+ years ago.
