Suicidal or not?

My boyfriend quit his job, threatened to hang himself and stood in a bridge contemplating jumping off then resigned his job of 7 years. I came to look after him and when he doesn't want to do something for his own good he says he'll just jump out the window. Apart from that he can shower, eat, sleep and play playstation.

I've been suicidal before and I was completely different. I had to keep going to hospital to be given sedatives because I couldn't sleep kept panicking and was always depressed.

Second time I was withdrawn from everyone and lost a lot of weight while I was already slim and then I swallowed all my anti depressants.

The third time I locked myself in the bathroom for a year. Didn't shower for a year and lived out of a kettle refusing to cook and sometimes I'd eat my own shit thinking god will help me if I do that.

That is crazy and suicidal. I was diagnosed with psychotic depression.

I hope he's not using suicide threats as a card. Being suicidal is not easy and needs to be taken seriously.
