Still learning about him

My ex and I share the same group of friends. I believe we’re on good termsish now since we’ve both been graduated from high-school for 2 years, Grown more mature, and he contacted me in December to apologize for everything that happened between us (Although he was drunk texting so I feel entitled to an actual in person apology since my boyfriend got one).

My boyfriend and I ran into one of our friend (my ex’s best friend) yesterday while we were walking around downtown, and I learned he (ex) was on a Navy boat in Asia. Coincidence he decided to contact me and my boyfriend RIGHT BEFORE leaving 🤷‍♀️ Guess it was still eating away at him and he wanted a clear conscious before leaving. I respect that HOWEVER, I do think me and him need to properly meet up and talk. There’s a lot of confusion on both our ends that need to be cleared up, and I know him and I both would benefit mentally if we were able to finally close the door on our chapter. Again, he drunk texted me so I think I’d rather talk to sober him. I would like for us to be friends again, but for his mental sake, we can’t. I never really had romantic feelings for him (long story), and he fell head over heels for me when I tried to tell him it was a bad idea. We ended up dating for 3 months before I broke it off, he was greatly heartbroken, and we were friends again for a short time 7 months later before we graduated, kissed a few times until he ghosted me completely after I told him we shouldn’t be doing this. I believe all the blame is on my side, and I was never a good friend towards him. I hurt him a lot and I just want him to stop blaming himself for it.
