So my friend was with her ex for about a year or so, and they split about 3 months ago. He had a lot of mental health issues that she found extremely difficult to deal with and so ended the relationship for her own wellbeing basically. She kept in contact with him because he was in a very fragile mental state and she was worried he was going to kill himself which he had threatened to do many times. She started dating someone else and things have been going well, but the ex was still constantly texting begging her to get back with him or come and see him etc, and sending photos of him self harming, making threats to kill himself if she didn't speak to him. I recommended she tell his family so they can support him as it was taking its toll on her. The new guy found out about it all and naturally wasn't happy, I think it all kicked off and the ex found out about the new guy, new guy gave her an ultimatum of him or me, but I'm not 100% sure what happened after that. Next thing I know, the ex has been found dead and now my friend is feeling so guilty as if she is responsible because he told he was going to do it. I'm struggling to find the right words to say, I've said all the usual, that's awful, I'm so sorry, it's not your fault, you did what you could, he was unwell etc but she's holding on to the fact that whoever she informed of what he said he was going to do, didn't act on the information so that's why he is now dead and she feels she should have done more. I don't know all the details because it feels a bit morbid to ask so I only know what she has told me, but I think she told someone from his mental health team by the sounds of it and when they did actually go to his house the next day, he was already dead. I don't know what to say and naturally I am worried about her. We work together and only me and the manager know, but as she is normally quite chatty and gets involved in office banter etc it's quite clear to everyone that she is upset. I don't think she should be at work but I'm also glad she is so I can keep an eye on her. Does anyone have any advice on how to help someone going through this situation? Thanks.
