If you rejected someone due to misunderstanding but when you realized, it's too late so you regret it, what would you do?

A year ago, I dumped my boyfriend because I unfortunately got evidence that he was being unfaithful. Soon after breaking up I was considering hanging out with a guy from my school because I thought he's nice. I know him since I was in 6th grade and he was in 7th grade, he is a year older than me. I wanted to get to know him more and thought that if things go well maybe I can ask him out. But I wanted to wait because I just broke up.

He was applying to universities abroad and he got accepted into one of them, so he was leaving in a few months. I thought I don't have much time in my hand so if I want to go out with him then my time for that is very limited. So I asked him to go out with me at least once before he leaves. He started to beat around the bush and it was clear that it's a rejection.

Soon afterwards, I was back with my boyfriend. A lot of things happened and I decided that he deserves a second chance. After that I was talking to the school guy and he told me that he rejected because he thought I wanted a rebound and that's unhealthy. He totally misunderstood me so I made it clear that I didn't want a rebound and I did it only because he is leaving soon. He said that he would have 100% said yes if he knew my reasoning earlier. He even asked me if I would still go out with him, I obviously said no because it's too late!

He still tries to make me doubt my boyfriend, and always suggests finding someone better. I'm currently applying to universities abroad and he said that if I go to his university then he will welcome me with open arms and help me with anything that I need.

I am not sure what to do with this guy. Would you guys behave the same way if you were in his place?
