Perspective: Married, I stream, and I have a full-time job.
I do 4 days/week right now, and do 6pm to about 10pm (plus or minus an hour). We just barely make it work. But why do we make it work?
Basically, we do streaming as a team.. It's been fun, and we've grow a small little community.
So what are your BF's motivations? His goals? Your goals? Do they align, can you support each other? How can you make this a two-way street?
