Some context: Me and my friend have been close training partners for several years now and we've gotten through some crazy workouts together. He's always been there to push me through slumps in training and I wouldn't be the runner I am today without him. We had a pretty good system going until recently when he met a new girl during his altitude camp. Since then he's been really distracted talking with her and skipping workouts with me to hang out with her and stuff :((. I know I should be happy for him but the girl is from a rival school so him hanging out with her is like fraternizing with the enemy and I'm worried about him giving away our training secrets and jeopardizing our league title defense in XC this year. Worst of all the girl isn't even that great, maybe a 4/10 at best so I can't really understand why he's throwing away his future and the future of our team for this :((((. Please help me. What should I do? Should I try to break them up?? Should I just let him go??? Keep in mind he's one of our top scorers in XC so we really need him to be focused on defending our league title from last year.
Before you even ask I can't post pics for privacy
