I’m back at home at the minute due to a change in circumstances. Me and DM have a good relationship and she enjoys my company, I pay keep and help out a bit etc.
Today DM was working and yesterday I lost my job so have been up all night upset. I woke up around 1pm had a shower to try and feel better, then at 2 heard DM come in from work.
Came downstairs to her raging, asking why hadn’t the pots been done. I said those are last nights pots and I didn’t even eat, I haven’t even been downstairs yet today so didn’t even know they were there or I would’ve done them.
She’s just received a letter from someone who she owes money to which was obvious why she was in such a foul mood.
I said let me eat this butty and then I’ll wash them.
She went upstairs to ring whoever it was she owed money to and I started the dishes.
She came downstairs and said oh it’s fine I’ll do those. I said don’t worry about it it’s fine. She goes “GIVE ME THE SPONGE” 
I said honestly it’s fine I’m halfway through now.
She gets really wound up and angry so I said do you know what, fine, go ahead and left her to it.
She then says “I like to wash my dishes with washing up liquid not just water”, implying that I hadn’t used any washing up liquid. I turned around and lost it. Called her an arsehole, told her to stop being such a fucking control freak all the time. Clearly it’s not about the dishes, she just wants someone to take her anger out on about the money she owes, even though it’s no one but her own fault. I said just because I couldn’t do my job and lost it doesn’t mean I can’t do something as simple as wash a fucking plate.
She tried to act timid and innocent to make me seem neurotic, but she really didn’t push me.
Was I unreasonable to blow up like that? Was it an overreaction because I’d lost my job and feel like shit? Or was she being unreasonable and a control freak which made me blow up?
