I wanna rekindle with my old friends- idk how as it ended weirdly

22F, my bachelors is about to end and im planning to quickly leave for abroad afterwards, as all my family are there.

FRIEND 1-during my second year, I had a guy friend who really liked me , however i didnt like him back was pretty obvious about it, and two months after that i had a bf and brought him to my uni events often, even then the guy friend used to talk to me nice and all. After few months he got a gf and completely removed me off all socials, and started ignoring my existence, i thought valid cause he has a gf now. but the behaviour was the same even after they broke up, and it lowk broke my heart cause i thought we were friends and maybe he felt like i was leading him on . Now i dont want my uni to end and us being on bad terms even after all of that and i wanna make aconversation with him to sort it out.

FRINED 2- we were bestfriends for a long time 3 years. during our third year we had a fight, it was outta nowhere and during which she handled it badlyyy and said some things about my past that had no correlation w her and the situation, the things which i had told her as a very close friend and was a trauma of mine . its been a while and i have already forgiven her for what she said to me. i dont wanna be bestfriends w her but atleast talk nad sort it out so we arent really enemies. but she is not the kind of girl who goes to past. IDk what to do on this as well.

Ik people dont go back to their past and do thi stuffs, but im not the kind of person who can move on so easily from this kinda situations. I have lost friends here and there outta nowhere and i dont wanna be in bad terms with people. What should i do? Is this slefish thing to do?
