Dear new Member~
Welcome here to the Forum, a good place to gain perspectives from others. It can be very upsetting to have someone text they are going to harm themselves and if you have a sensitive daughter it is not surprising she becomes overwhelmed.
As I don't know the circumstances of your marriage or parting I would not know why he contacts you all. I guess it could be a genuine cry for help what very down and frightened, equally it could be a method of trying to gain control, and uses this as a threat, pushing the sympathy button.
Either way I think your GP has given you the best advice, get the police or ambulance (via 000) to do a welfare check. Be prepared though for him to say there is nothing wrong and you are trying to be a nuisance. Some people have very smooth tongues and present well.
I'd suggest you keep the texts to show he instigated the matter.
I'm not sure you can do that much more at this stage, you have looked after his welfare and done the right thing. Is there any reason your daughters cannot block his number just leaving you to deal with any future occasions?
If you would like please let us know how you get on, you are welcome anytime
