So my players and I have a group chat where we can all talk. This past week one of the players has been non stop trying to make me mad in the chat involving D&D mechanics and stuff like that.
He was saying "I can do this and that" and I said "no" so he said "bet". I told him to stop, but he didn’t stop. He also got mad that next campaign I am adding in some new rules to our group and changing how we play because, in this campaign, we don’t use some 5E rules. After I told them what we were changing he started to insult me and how I DM. I gave him many warnings to stop.
I gave him many warnings to stop everything he was saying or he will regret it and even maybe for the whole group. He did not stop at all. He just kept going and going. Other players were telling him to stop too, but he didn’t listen to them either. So I left the group chat, and one of the other players made a group chat without that player in it. (He has tested me like this once before, but he has never gone this far)
We have a session in a week and I was wondering what I should do about this? Do I ban him from one session, just talk to him and try to settle whatever is going on with him, or cancel the next session until we can fix everything? I honestly don’t know what to do because of how bad the messages were in chat, and also because I told him to stop and he didn’t listen more than once.
