It sure sounds like he’s living his best life, while you’re suffering. I agree with other commenters that his dismissal of your concerns is not a good look, but other than breaking up I want to offer another idea:
- first you should stop showing up to all his runs. if he needs someone to bring him water, he should find someone who cares about his running as much as he does. you can show up to special runs, but it sounds like you’re stuck in a hobby you don’t even like.
- find people who like the stuff that you’re into and go out and enjoy some things! right now he’s living the dream: back-up girlfriend who’s there for everything he needs. he probably doesn’t see the need to do something you enjoy together with you because you are present for all things that he enjoys (attending his runs, accommodating his several runs/day). stop scheduling your day according to his needs and prioritize your own.
- this should bring you in a better headspace, build up some confidence, and should make it clear to you what the status of your relationship really is. if he misses spending time with you, that would be an opportunity to bring up this vacation again and set your expectations (and push to enforce your newfound boundaries). if you find out neither of you actually misses the other person, I guess it’s really time to ask yourself why you’re in this relationship.
ETA: if you do want to break up, that is valid as well! your needs are valid <3
> calling me selfish and a brat for ‘whining’ that we don’t spend much quality time together anymore
So it’s clear not only that doing things together isn’t something he’s interested in, but that he calls you names because it’s something you are.

What did you expect? When you were eight, he was thirteen!
(just kidding about that part)
