DS is 12 months old, mine and DPs relationship hasn't been that great since. He has been away with work more than he has been home, and I had crippling PND plus was made redundant which means I have been stressing about finding work, and perhaps taking it out on him by being moody when he has been back. He doesn't help at all with DS, but tonight he just stormed out and took a lot of his stuff. I have no idea what's wrong, bar perhaps him going through my phone as there's a few messages to my best friend saying about how I'm struggling etc, which mention him. She isn't a mutual friend and I trust her so it's not like anyone he knows would find out (if that makes sense) so he wouldn't be humiliated, and it's all things I have tried to talk to him about before.
AIBU to find this sulking off the final straw? I have no idea where to begin in leaving, but honestly I'm a mess.
