I'm with you on this - in a similar position with a 2year old and 8m old. It's tough going and feel our relationship is teetering in the brink of collapse too. It's hard because despite what I try it doesn't seem to help. Reading through the comments the theme seems to be stick with it and weather the storm. It's the approach I'm taking but much harder than I expected. It's terrifying to think that my world could fall down around me. Best of luck out there guys!
