<human>: Provide a brief overview of the text.

This isn't as huge a problem as most I see on here, but I hope someone can offer me advice!

My boyfriend (Jack) runs his own company, which he set up a few years ago. In the last six months or so, they haven't been earning consistent money, and Jack and his partners are getting antsy. There was an overseas conference a few weeks ago which Jack thought was unsuccessful, and he believes was the final nail in the coffin.

My problem is, that ever since then he has been incredibly stressed and sad. I've been trying my best to be supportive, but his stress is really affecting his ability to concentrate.

Over the two weeks since the conference he has:

a) left the gas on the hob all day which leaked all over the apartment

b) forgotten his keys in a training centre an hour from our home

c) run a red light, despite me telling him to stop multiple times. He said he just wasn't concentrating.

There have been many smaller incidents, but these were the big ones. After the keys incident I told him off, and asked for him to try and concentrate more, and he reacted snappily and quickly became quiet and despondent. 

I'm worried about his safety, my safety and our pets safety if this continues, but I don't know how to bring it up without stressing him out more, and even if I do bring it up, I don't know what to suggest to help fix it!! Does anyone have any advice?
<bot>: Boyfriend's stress is making him forgetful and it's worrying me. Don't know how to approach him, or what solution to approach him with.
