If an undesirable situation keeps repeating itself, then there is bound to be a reason why this keeps happening. This likely involves you or someone else opting to put heads in sand rather than face the issue or have a long-overdue and slightly difficult conversation. A way forward needs to be agreed; you can't keep supporting someone or a situation in ways you are. Complacency seems to have set in and it will be up to you to take action in some way to bring about a fair change. This can be done much more easily than you think!
