Hii guys something happened and I dont know if I should feel guilty about it Can yall help me out?

 Alright so there was a weird relationship going on with my frien and her ex for three months neither of them accepted to call it a relatonship but just flirting because online dating is stupid apparently anyway this dude kept breaking up and coming back ans sulking and just overall being impossibly immature and for some reason they always forced me to thirdwheel them even though I was really annoyed by it especially because I used to like my friend back then but she rejected me anyway then that guy quite literally lied to both her and me AND EVEN DARED TO SAY I BETRAYED HER WİTH A FAKE SCREENSHOT so there was a big drama my friend promised shed never accept him back unless Id forgıve him (she accepted him anyway and forced me to forgive him bc he said hes leaving unless I forgıve him) then I got into a money problem and my dream skin so I had to ask someone for debt and that guy has said that hed even buy me things for me to forgıve him so they could be together so I thought I could ask him and I did and he did help me get the skin but before I could pay back they fought yet again and he disappeared so I cant pay him back I feel bad and eviil but logically it wasnt my fault what should I feel
