Im not sure what to do with my break up

Me and my boyfriend broke up after a buildup of unresolved issues in the relationship. He was going through a lot personally, but he didn’t communicate most of it to me because he felt I would get defensive when he was upset. I do admit that I sometimes reacted defensively when he brought up problems, which made it harder for him to feel comfortable opening up.
Because of that, he started keeping things in and not fully expressing how he felt. Eventually, everything built up and led to a breaking point where he expressed his feelings all at once, and we ended up breaking up.
Even after the breakup, he says he still has feelings for me, but he doesn’t want to talk in person and avoids meeting face-to-face conversations. I feel like this situation is serious and complicated enough that an in-person conversation would help us fully understand what happened and whether anything can be repaired or properly resolved.
I love him so much and the week before we went were so happy and constantly went on dates. Even after 2 years it feels like he just threw it away.
And to add, I am pretty bad at communicating, but he would always tell me to communicate how I was feeling, and but when the time came to him, he wouldn’t tell me how he felt so which also led to our break up.

What do I do? I want to talk in person and he is leaving for vacation tomorrow and I asked to meet up today but he said he was busy but will let me know. I feel like talking in person will be so much better.
