"i mean they talk to me about whatever interests them, which most of the time i couldnt care less about"

I think I see a problem in there. I'm sure that like most people, they want to talk about stuff that's really, really interesting. To them. And very likely to friends.

Hetero guys traditionally got by without being interested in what women talked about, but at least the heteros had sex and marriage to fall back on. To cover those conversational lapses and moments of wandering thoughts.

I'm not sure a BL has the luxury of saying, 'oh, sigh, boy talk, yak yak yak.'

Not saying that taking more of an interest in their fascinations would quickly put you in place to change their lives for the better, but it couldn't hurt. You can't really fake an interest unless you're a very good actor.
