Does it all stay the same?????

I have been known to have a lot of "Fuck It" in my system. Sometimes when it's necessary and sometimes it's too much.  I know it's not always the best to not give a lot of fucks, but I can't help it.  I was tested with this earlier this week.

I have an old friend (not fuck buddy/boo thing)  who is bisexual and he was one of my only gay/bi/dl friends, best friends really. We haven't really been close in a while due to him doing some fuck shit that I just couldn't forget enough to continue with the same friendship.  We had mutual friends, and we all live in different places now.  And after getting together with my big bro "Donny" when he came in town,  who knows him and lives in the same city...I heard some disturbing shit.   He was a little hesitant before telling me, but he finally spilled the beans.  My old friend (let's call him "Mikey) has been out there tricking off.  And by tricking off, I mean selling his body parts and sexual favors for money.  I couldn't believe that shit.  Honestly, it's not something I would have put past him...but not something I have ever though of him realistically doing.  I was immediately scared for him.  For the past couple of years my attitude towards Mikey has been "Fuck Him"...but now I feel he is in trouble.  I acted "hard" in front of Donny, like I didn't care and he deserves what ever he gets.  But in reality,  I rode back home in complete silence.  

Donny told me Mikey was advertising himself on various websites/phone apps and it was a CONSTANT thing.  He was offering services and wasn't mentioning protection.  It hurts, like seriously hurts.  Mikey is an extremely handsome, attractive guy who can probably have any guy he wants in a relationship.  I just don't know what would make him so desperate and what he can be going through to resort to having a fucking price list for "services".  I heard of this shit going on in the gay world,  but I never thought it would hit close to home. We come from similar families...HE DOESN'T HAVE TO DO THIS. His parents are more than able to help him, and they always have.  The last I remember, they had a great relationship.  

I just don't know what to do, if anything. I want to call him and help him somehow.  How?  I have no fucking clue.  But for one of the first times, the "fuck it" in my system is wearing off.  I feel like a horrible person, because I kinda threw him away after we had out disagreements and after he tried to work it out, I turned my back.  I don't know what to do.  Once again, excuse my random venting.
