How would you handle your narcissistic father reaching out

TL;DR: I went no contact with my father for 3 years after years of (which I now painfully accept as) abuse, neglect, and emotional manipulation. I am now hearing from my brother that my dad wants to speak with me and the rest of my siblings again after admitting he's "could've done things better".

My dad wants to reach out after 3 years of no contact. The final straw for me cutting him off was him forgetting my high school graduation back in 2021 when I told him 3 separate times in advance.

He forgot anyway and when I reminded him, he didn't sound proud of me. Just nonchalantly said "oh. Congratulations". Then a few days later he sent me 50 dollars without saying why.

Right after this, he forgot my birthday all while guilting me because I didn't want to go to his wedding

(Not only did I just not want to go. But I was actually just beginning a course that I already had to quit the first time and waited months to reapply and get back in. I told him this and he acted like it wasn't important.

He did this while I was in high school too. He had to reschedule his wedding the first time due to covid and got mad at me because I said I couldn't go because his wedding was ON MY BIRTHDAY and the fell on the weekend I began school)

This is just one example of his self absorption and I'm sure you can see what kind of person he is based on this alone

To add insult to injury, he pretended like everything was fine and dandy after I told him I wasn't coming. But he was actually upset. He ran off and told my sister, using her like a little minion to come and confront me after pretending like everything was okay.

So again, you know what kind of person he is from these facts alone. There was more to this and how he spun the narrative to make me seem like this ungrateful bratty child to the rest of his side of the family, but I don't want to this to be too long so feel free to ask for any further context.

Anyway. Come last week and I found out from my mom that my oldest brother got a call from my dad and was basically complaining that he still doesn't understand why we cut him off even though we tried for years to explain why we felt so hurt.

Shockingly, my oldest brother got him admit that he could've "done things better", which is the most mild form of accountability but the most accountability that I've ever heard him take in my life at 23 years old.

My mom has suggested doing a family therapy session in the past but my dad rejected the idea basically saying we're not going to "guilt" him for doing stuff he knows he didn't do. He said that we can start on a clean slate and move forward and that he'll wait until we're ready.

As you can see, that didn't go in his favor. So since he reached out to my brother (which again was shocking because they both have had major beefs before) and actually said he could've done things better...is it worth a shot?

I told myself that holding on anger is doing me no favors and that I'll forgive him since he's not in the position to utterly destroy my life like he did when I was a kid and dependent on him (me and my two older brothers lived with him in a different state for about 4-5 years before coming back home with our mom in our home state) and that id keep him at a great distance.

The only other reason I gave myself to have minimal contact with my dad is that despite being narc, he's not the kind of narc that deliberately targets people with bullshit hurting people..he's more so an idiot with a massive ego and wants people to give him that validation. He's demonstrated empathy occasionally but it's usually very much distorted and self centered (for example, giving money to the homeless because he thinks it will give him good luck).

What are y'all's thoughts on my dad?
