Partner broke up with me to focus on disc golf

[u/microcrave]

We had been together for 3+ years. About a year and half ago he got into disc golf, he introduced me to the game and I enjoy it. I wouldn’t always play the whole course with him but I liked walking with him while he played and was always encouraging when he talked about it. Now he has gotten very serious about disc golf and decided to pursue it professionally, I was supportive of that, whatever. He’s determined that he’ll need to spend most of his free time practicing so he won’t have time for a relationship anymore. We had a few other solvable issues, and otherwise a solid relationship, but his main reasoning was disc golf.

With that, I have a few questions;

How likely is he to make it to the professional level?

Are the discs laced with something?

and most importantly, Wtf?
