Should I kick one of my groomsmen out of the wedding?

Tldr; Groomsmen is being very flaky two months before my wedding. Should I just kick him out of my wedding party?

I got engaged to my fiancé in 2018 and we planned to get married in the summer 2020. I asked all my groomsmen to be in the wedding party in the Fall of 2018.

Because of covid we had to postpone a couple times but now we are about two months away from the wedding day, and very excited it’s finally happening.

My bachelor party is one month away and this GM who previously said he was coming now he says he can’t make it because he’s “not in the right head space”, “focusing on his career”, and “concerned about paying for it”. Which I was fine with, annoyed, but whatever that’s fine.

I asked him if he thought he could still be apart of the wedding party and his response really put me off. He said “well what would my responsibilities be?” And “what’s the date again?”. Mind you that I’ve sent him countless emails and reminders over the past 2 1/2 years now.

I’ve been close friends with him for the past 10 years, but now I’m questioning if I want someone there who doesn’t seem to care enough to put any effort into the biggest day of my life. Would really love to hear what you all think.
