Friend group falling apart

Sorry this is going to be long. So, for the past 2/3 years I’ve had a very solid friend group with me and 3 other girls. The 4 of us are in a group chat together and over the past year we’ve become even closer and they mean everything to me. However, the day before New Years eve we all got into a massive fight on the group chat over a stupid NYE party that didn’t even matter. The fight kind of ended up with 2 sides, me and my friend J against the 2 other girls S and M.

After the fight I told everyone that we are all sorry and agree the fight was stupid. Everyone sort of agreed and I thought things would just go back to normal. I personally apologised to M right after as I had said some mean things to her, but she didn’t reply to my message and still hasn’t to this day. Me and J kept talking in the group chat like normal and offering plans for us to do but S and M werent replying, and still almost 2 weeks later neither of them have talked in the group chat.

I decided to privately message S a few days ago and ask her what was going on. She said that she wants things to go back to normal but they dont know what to say, and that M is very angry and stubborn. I didn’t know what to do so I just told her that me and J have no hard feelings and we will wait for them to be ready to talk again.

As I said, it’s been almost 2 weeks and they still aren’t talking in the chat, even when I messaged it to say I had to be in isolation they said nothing which made me feel like they didn’t care. I feel like I’ve said everything I can and I just have to wait, but idk how long to wait. Me and J are both having these feelings. What do I do?!
