OK so Aaron (my fiance) has a younger brother named tyler he is 15 and his girlfriend who just broke up with him killed herself not to long ago and since then tyler has been very depressed I understand it is going to take awhile I have lost a lot of people close to me but sometimes he talks about how much he hates his life and how he wishes it would just end and when I get worried and try to talk to him about it he says cas I'm just kidding I wouldn't do that but when he says it he seems serious aaron says he just wants attention but I don't want to let this go and then him do something that I could have prevented
Help thank you
