Sorry for long post, need some advice feeling quite upset. Had a huge blow up with my partner resulting in him threatening suicide and don't know what to do. He is facing redundancy and found out he didn't get a job he applied for. I'd spoke to him via text a few times in the afternoon and tried to be supportive, telling him it'll work out and sending job adverts etc.
After work I got home and said a throwaway comment about me being stressed as work is very stressful along with other commitments and struggling to find enough hours this week. The redundancy is obviously a stress to me too but I know it is happening to him and it probably was insensitive to say I was stressed. He didn't say anything but was giving me silent treatment and I did realise perhaps it was selfish to say I was stressed so tried to change the conversation to him. He was upset later on about his career so comforted him, helped him apply for other roles and stayed up late to chat etc.
This morning I was working at home and I asked who was walking dog today, I admit I was probably short to him but was in my own head trying to plan the day. Resulted in a massive argument and I then snapped at him as he said that he does everything and I should be able to shoulder my stress and not make everything about me. Says I only care about impact of his redundancy on myself. He was screaming, threw things at the wall and then told me he wants to kill himself, everything is shit and that nothing he does for me is good enough. Left the house with no phone for over an hour while I'm frantically worrying that he's hurt himself.
He came back and have tried to talk but he just keeps saying I am selfish. I can see why he is hurt but feel his reactions out of order and effectively blaming me for wanting to kill himself. I said I feel unsafe when he reacts that way but he then said he feels unsafe as he doesn't know what he might do to himself living in this house with me. I know he is hurting and I have tried to support him but feel like he is twisting things to say I am only worried about myself and that I'm driving him to suicide. This is probably the 3rd time something like this has happened in a few years and I can't just pretend things are fine.
