Having a sucidal boyfriend

I have been dating a boy for over a month now and its going great! but one thing always pushes the barries further apart. He's a great guy, makes me laugh, smile to hard.

Why does the thing that always hits me is that he's sucidal and it drags me down he was a whole lot worse a year ago and i had to break up with him because i'd sit in my bed crying and frustrated at myself...

We're back together and he's better. Normal...Almost. Whenever he says im gonna do it. I feel afraid, feel like it's my fault. Soon as he says that sentence I'm angry then straight after i cry. I normally feel it coming because he's so angry at me and i know i haven't done anything but soon as he says it i automatically feel like i have.

Any support will be muchly appreciated

I need help how to act calm when this comes again.

Is he getting any professional help at the moment? Does he have triggers which cause him to come to the conclusion that suicide is his only way out?

He sees a therapist once a week

He threatens suicide when he's angry with you?

For your own mental health, think carefully whether you want to stay with this person. I knew some people who used to be in the similar situation, and in their cases their partners, at some points, started using "suicide" as a mean to control them. Obviously, I'm not saying he will do that, but this is something you should be aware of.
