<human>: Long story short, he saw on my birthday that a person added me on Facebook, a person I kissed two years ago. He flipped shit and then we made up, but deciding not to have sex. But we still cuddle and hangout and shit. 

Yesterday, some dude I haven't spoken to in years and never had any kind of relations with posted on my Facebook saying he likes my dog and my "picture taking abilities". (For the record, I have a japanese akita, so he gets a LOT of attention). I'm annoyed at his comment but I say thanks because that's the polite thing to do. My FWB gets super pissed at me and says he can't come to my graduation because of this. 

I'm fucking fed up with Facebook drama. It's stupid. I haven't slept with anyone, not even attempted, nor flirted. My heart is set on this guy, (which yes, that's a whole different story, one I need not be lectured). 

My question is, what is the best resolve to this? How do i deal with petty drama like this, even though his trust and friendship is something that is very important to me?? We are going to talk this weekend. Am I in the wrong? Do I look shady and not realize it? What can I do to help him trust me? Let me have it reddit. Give me some clarity.

Could you distill the essence of the text into 1-3 sentences?
<bot>: best friend is also friend with benefit.  He is jealous over petty facebook drama. How do I regain trust and am I in the wrong?
