Happened on Sunday after work.
1st conviction 6.5 years ago just before we got married. Was touch and go whether I would go through with wedding. He has a history of alcohol issues prior to 1st conviction, lost a job through drinking, offended friends and family, arrested for drunk and disorderly.
But since that 1st conviction things have been so much better, almost non existent until fairly recently when a few incidents have crept in, drunk at work 3 weeks ago (he works in catering so v long and unsociable hours with drink readily available, also big culture of drinking), one night with family where he was supposed to be looking after DCs so I could have a drink (1st time since dd born) but he got drunk instead.
However those are only instances I know about, I feel sure there are more. After the incident at work (formal warning given) he went to GP and made appointment at alcohol service but had to work so cancelled it.
He rarely drinks at home or in social situations where I am there (watching him like a hawk usually) but it appears to be linked to stress and working, 1st conviction exactly same situation.
I feel I have no choice but to ask him to leave and for us to temporarily separate, we now have 2DCs, DS 2.10 ans DD 5 months.
this isn't what I want really but think this will shock him into getting help and stopping altogether, I have asked him to do this several times but he seems unable to do this.
He is a fantastic father and we generally have a good relationship, together for 12 years, married for 6.5. Have had a very tough 18 months, business went under and we were very nearly bankrupted, managed to settle debts but still owe friends a family thousands. It was hugely stressful but actually payment plans in place and we are, I thought, slowly returning back to normal.
Evidently not. 
Has anyone experienced drinking issues like this?
Any advice would be appreciated.
