He told my sister, after being odd for a few weeks, that their marriage was over last night. He had changed as a person. He wanted to be single. He has met someone he wanted to cheat with, but didn't.
She is heart broken. He said there was no discussing it. Then this morning he has text her saying he made a mistake and he doesn't want to end things.
Who the fuck does that to someone. She thinks he has met someone else.
I have seen good advice on here for similar situations, but can't find the old threads. Is there anything practically that she should do to protect herself? I have made her change the passwords on all her accounts.
I'm largely stepping back as it isn't my marriage, but is there anything I should be doing?
