of course you are tired. you ahve two small children - a faull time job - plsus an adult who because of his depression does not help.
depresison is not his fault - but it is his repsonsibility to take charge of it and own it and take steps to combat it.
you well you ened support. you ened ot see a counsellor to talk thru strrategies, setting boundaries to deal with his depression.
you need to find a way to release teh birden so that he - for example - takes himself off ot a friend for couple days; goes to the gym, speaks to the Gp about a prescription for exercise at local gym and therapy for himself.
you need to be strong about laying down the law on suicide threats - tell him - you make a threat i will call 999, i will take your threats seriously. you need help which i cannot give you.
talk to rethink or counsellor about supporting a depressed person - read about depresison fallout and think about the strategies - i found this book excellent -

you've been doing for years - so did i...
read the chapter on impact on children growing up with a depressed parent. yours are young but it makes sobering reading.
it CAN be mitigated - plenty of time with upbeat positive people for example.
you might want to stay with and support your H but you have to be prepared to set the boundaries as you now have 2 dc to think of.
it isnt fair on them to hear their dad saying "i am going to kill myself" espec if it just becomes a mantra...
my nowexP is i can see falling into his autumn depression - unable to get on top of tthings, turning up at the door for attention, looking inwards "dont you understand "
he was depresssed with me, depressed without me. nothing i do or dont do changes that. only he can work thru it.
if you are going to decide to support him you need to think carefully how you can do that and care for the children, deal with your tiredness etc - individual counselling, maybe family therapy together might really help - i did attend family therapy with my exP - it was useful in that they tried to tell him to take responsibility for his depression - which at least for me validated the idea that it was HIS depression - not mine....and they urged him to seek proper help. (he didnt but that is another story).
it is good that you are getting this out and maybe beginnig to think longer term -as you now have DCS - how to manage the situation - his depression, the DCs, your role and the support you need.
and you do really need support for you - go to your GP, get tyourself referred for NHS counselling - the six sessions may just help you to process and analyse and think about you and the Dc in all of this - and make decisions for the way forward.
whether that is ultimatums to him or whatever.
