Complicated apology

A friend of mine had a party 3 months ago. I was quite drunk and a couple of days later my friend told me that a male friend of hers had been to visit saying that I had upset him at the party by something I had said but assured my friend that he was concerned that I wasn't t my usual self. Mortified I tried to phone this guy to apologise but couldn't get through so I sent an apology text message saying I was really sorry I had upset him, I couldn't t remember what I Had said but I realised that was no excuse. He hadn't replied after a few days so I sent another text more jokey telling him I wasn't scary and asking him to communicate. I then got a horrible text back inferring that I was playing a dangerous game and never to contact him again. I saw him out in the pub and smiled but he blanked me. I am not someone who gets nasty on drink so I knew I hadn't been abusive. we were all meant to be having Christmas dinner together at my friends but after he blanked me I told my friend I couldn't go as I suffer from depression and anxiety and wouldn't be able to deal with the atmosphere. He went for dinner at our friends I popped in for a drink and I maybe got a hello but that was it. My friend tells me he wants to sort it out and he had told her that the pub wasn't the right place to do it. I m confused as he didn't t smile back. He also told her he hadn't been in a good place that night due to a relationship. I feel very angry with him now but my friend doesn't understand my anger.I m not sure what to do next and would appreciate any advice thanks.
