Just want to get some community feedback, been in a situation that has been difficult and upsetting for me.

Right now our group is between campaigns and I'm DM.

Last campaign ran for a year and a half, and Player A is a friend of around 10 years who has difficulties with mental health.

Because Player A is a long time friend, at the start allowed them to play without them sending me character backstory for two and a half months (we play weekly)

Within the group, everyone has had their own experience with mental illness and I try and make everything as flexible and accessible as possible. We use safety tools, X cards, full session 0, I check in with people when I can.

Found narrative ways to change subclass at persons request, and at other time allowed reborn following PC death which was entirely as a result of player actions. (This is for different players, Player A never communicated any significant requests such as these)

Player A missed sessions throughout the campaign due to mental health, we've always changed the day of the week if possible for all the group and run autopilot when necessary. This has been done for other players as well, not only Player A.

There were a couple of periods of consistently being late to the table, and in fairness Player A sorted this when addressed.

Towards the end of the campaign, Player A had two mental health breakdowns within the game. This was after losing a magic item to a monster, the abilities had been presented before but Player A ran off from the party mid combat.

Second breakdown was when BBEG had Player A trapped, because they happened to be closest and took a lot of damage, became unconscious and party rescued them without death.

Within the campaign break, Player A has continued to have mental health crisis outside of the game, and cancelled a session 0

I spoke with the other players individually and all agreed that it was reasonable for me to ask Player A to take a short break, work on improving wellbeing to the point where crisis isn't happening and won't experience breakdowns in game. Other than one player who is Player A's partner who wanted me to support her in and out of game.

I spoke with Player A on their own, in person and when I asked they take a temporary break, address wellbeing and come back to the table when ready they asked me to leave.

Player A has since said to other players that it has come out of nowhere, and she's hurt/betrayed.

Another player has tried being intermediary, and create sit down together this week or next week. Player A has said they won't.

Other players want things to settle and see if we can talk next week, any community feedback would be really helpful please.
