help please

ok so basically there's this guy lets call him (T), then there was another guy lets call him (V) this guy V was T's bsf ,me and V were bsfs for 3 years or smth but then he started liking me and shit so i completely started avoiding him and all that bcz from my side it was totally platonic and i liked T then eventually me and T started dating and me and V completely stopped talking like cutoff types then as we were in the same class we became really casual friends while i was dating T and then eventually V got over me too and started liking this girl K (my kindergarten bsf) they had a situationship for like 6 months or so before it ended on really bad terms bcz my bsf(K) didn't wanna commit to a relationship and had SERIOUS COMMITMENT issues eventually me and T broke up as well after 2 years 7 months as T cheated on me, now this is where the main story starts me and V started bonding and started becoming friends again he made me loved seen and cared for i mistook that platonic love for romantic feelings and fucked up and used him as a rebound while i still missed T, V started hating T for obvious reasons cuz he cheated and all that and did gross shit to me, well me and V dated for like a week or so till i realised that I don't actually like him and that im still not over my ex and that it is not right for me to date a guy whom my bsf (K) liked, i clarified shit with V and broke up even after that we were still friends until he blocked me on a random tuesday, I thought that it was a natural reaction for him to hate me and wasn't really bothered by it cuz at the end of the day it was my fault then months later i started talking to this new amazing guy i was completely over my ex as he had said and done ABSOLUTELY HORRIFYING things to me so i got over him pretty quickly thenn and after months of talking me and this new guy H started dating now, me and V are in the same class have the same friend group we don't even look or talk to eachother at all and its so awkward and now i genuinely feel bad for doing this to him toying with him for years when he genuinely liked me and i really do wanna apologise to him but it has been a LONG time since we talked and now i have a bf.

What should i do? Should i apologise to V one last time and expect nothing or would it be weird since i have a bf now and let things be as it is ? V reallllyyy realllyyyy hates me for doing this to him and i never apologised to him and he got even more heartbroken after knowing i have a bf but just to ease my guilt should i apologise or no ?
