<human>: Condense the text into a few key points

I value my boyfriend Eric more than anything in the world. He has tried my hobby (its a broadcasting/gaming/vlog type hobby) and has no interest but is extremely supportive of me, which is fine. I could wax poetic in the ways Eric has changed my life for the better and how wonderful he is, but I would rather be succinct.

Through mutual friends, I came across a fellow enthusiast of my hobby and we began working on it together. I love what I do so - understandably - emotions run high. Does anybody have advice on what I can do to ensure that our friendship STAYS that way? I have no interest in a relationship with this person and I think my feelings are simply due to my emotional attachment to the hobby. I suspect this friend is developing a crush for me, but I can't control that.

Thus far, my plans are to always prioritize plans with boyfriend over broadcasting plans, start limiting my time with my fellow hobbyist and focus on other areas of my hobby, and try to usually have other people working with us when we work together in order to ... spread my feelings out, I guess? I am not concerned with physically cheating, I have self-control over my behavior - this is an emotional problem. Finally, if I see myself continuing to grow an attachment I am going to have to sever the friendship. Due to public scrutiny from our following and fellow enthusiasts, I will probably drop the hobby as well. That's fine, I have other hobbies... but this is something I have been developing for the past few years and I spend 10-30+ hours on it per week. It would make me really unhappy to up and quit.
<bot>: Please advise me on ensuring productive friendship STAYS that way. I don't have room for a crush in my life.
