AITA for not supporting my friend at his worst when he didn't include me at his best

Hi I'm Lance and my friend is Link.(Not our real names. So link and i have known each other for a little more than a year now. We met at collage and we had a lot in common We used to hang out all the time and do lots of fun stuff together like go to concerts, college events and all sorts of stuff We were almost inseparable. But one day it reached a point where he would say he was busy and i respected that. Later to find out that he was at a big party or some other event we would normally go together from socials. Now i would still invite him to events i found but he would ghost me for days and only reply later. I asked him if i had done anything wrong and he said that i was overthinking things. Then finally he just stopped speaking completely and i was fine with that. Because you know, people come and people go. It's life So i come to terms and continue with my life and meet other new and fantastic people Anyway a few months go by and Link texts me after a while After the akward pleasantries, he gets straight to the point and tells me that he's in trouble and needs some help I ask what kind of help he needs. And he tells me that he needs some money because he blew up his while partying at some party gambling meet he went to I ask why he decided to contact me after all this time, and he says that its because everyone else ditched him and he would get into trouble with his parents if they found out I told him that you cut contact with me, so i really can't care to help with his problems as i have my own financial needs to cater to So he goes on begging until he just snaps and starts saying how i was never his real friend and that i was lucky to even have met him and other nonsense So i block him and keep going on with my life So am i the ahole for not assisting or should i have extended a helping hand?
