A bit of background first - when DH and I had a baby a couple of years ago he had a MH breakdown very shortly after. For various reasons there wasn't much help available to us and honestly, I'm still not quite sure how we got through it, but somehow, we did. He has since had counselling, recognises how close we were to breaking up and is thankful that we are still together.
Cut to today and I am weeks away from another baby and his MH has been progressively declining. His temper is short and he gets angry and frustrated over the tiniest of things. I have been gently raising this with him but it's not having much of an effect. It's basically got to a point where I cant be certain he is not going to have another breakdown, which 1) I am not sure how I would cope with now there are multiple children involved and 2) I don't think I want to be the one that holds us together again.
When he calms down, we have good conversations, he recognises the problem and agrees to urgent further counselling. But it's not long before he looses his temper and forgets everything. I am exhausted.
To be clear there is no violence, and I don't fear that. The vast majority of the time he is wonderful but I am noticing a worrying decline and I don't feel like I am in a position to give him the help he needs.
The only person who I can think of to help is his mum. For me and for him. But I know he would be angry at me contacting her (he knows I have told her about last time and asked her to keep an eye on him, and that made him upset initially)
Thoughts would be welcome please - any any advice!
