So, I met him 6 months ago. He is a nice guy, and I really enjoy hanging out with him. I noticed he has some mood swing issues, and eventually, he explained that he has been diagnosed with ADHD and takes medication. I was managing it quite well whenever he got mad at me over simple issues like coming late, responding to his texts late, or things like that. I would spend a whole hour convincing him of the reasons for those silly mistakes.

Anyway, last week, he invited me to his place for Christmas dinner with his family and other friends. We were having a good time, and at some point, both of us got drunk. I was joking around, and I might have presented myself as "being alpha" or something, which he didn’t like. So, he was trying to make a point by engaging in some jostling. At one point, he started feeling sad and cursed at me, saying how I always make him feel bad. Then, he got up and slapped me two or three times in front of everyone and asked me to leave his home. I left and thought that was it, and it should end there. He even texted me, telling me not to come back into his life ever again and how much of a shitty person I am.

The next morning, I noticed he had deleted all the WhatsApp texts and called me. I hung up on him, and later, he texted me asking what happened since he didn’t remember anything that happened that night. I was feeling really emotional and wrote that he made Christmas the worst ever for me. He didn’t seem very remorseful upon hearing that. He just said he didn’t remember doing that and that he was sorry. I’m not sure how to handle this. Should I cut this friendship off? And if I want to continue, I can’t forget what happened at his house and how to forgive him. I was expecting more remorse, which he hasn’t shown. So, I’m seeking your advice. Both of us are over 30 years old.
