Am tired and can't cope with ohs behaviour

[3rdbump]

Am having a shit time :(
Partner went out last night and didn't show up till 10am. Crying on the phone this morning saying if was the worst night of his life and shat had happened was horrendous etc .....He said his friend left him in town (10 mile from home ) said friend picked him up this morning and dropped him off at home. He came in stinking drunk and Refused to tell me what happened and went to bed.
He often drinks and gets jn states (pleas read previous posts on here) and turns up at stupid o'clock. I have a 4 week old baby to take care of as well as a 2yr old and our older too who are 10 and 11. I am also breast feeding which is hard anyway and working from home (self employed) and just exhausted and am afraid it's going to tip me over the edge into pnd. I am trying to stay strong and positive but it's difficult.
zhe obviously has an alcohol problem. He's not nice to me.
I can't afford to live where I do alone and the tenancy is in his name I have bad credit so estate agents will t look at me and no guarantor. I feel trapped.
Am sorry I just need to vent :/

Do you have any family around you? Could you stay with them for a while? Your OHs behaviour is unacceptable but if he refuses to change then you need to end thus relationship.

What's he like sober? Could you talk to him honestly about the issues then?
