On Monday, DP and I get back from a tiring and stressful (but fun) camping trip. Ever since, he's been an arsehole and I'm fed up. It started on Monday when he called me into the dining room to look at some photos of the trip. Before he put the photos on the computer, he answered a message on Skype. So, without reading the message, I said "oh is that DSS (I knew it must have been and he's the only person he talks to on Skype), how is he?" I ask. By this point my son had also enterered the room to look at the pics. DP snapped "he's fine!". 
when my ds left the room, dP launched a verbal confrontation with me saying the conversation was private and he doesn't want me questioning him about his son!! I said I'd only asked how he was!! He snapped back that the issue was that I'd asked in front on my son . Anyway he rattled on and on, despite me saying I wasn't interested in the contents of the convo, I was literally just asking how the lad (who's 18) was!! He wouldn't back down, continued to insist I was out of order and I should understand why etc etc 
I refused to argue with him and just said he'd took it the wrong way and I didn't wish to discuss it further ffs, but I was upset.
Last night was awful. We'd both been at work all day, I came home, went back out to shop and did a weeks shopping, came back, made tea for everyone (all whist dP is playing on the computer!) and later gave him a random foot massage whilst we watched tv. We went to bed smiling. Now, we have two bathrooms upstairs, the main one and the en suite. I don't use the main one unless I'm getting a bath so bypassed it on the way to bed and got ready in the ensuite. I noticed it smelt a bit and that someone had opened the window. "Someone has shit in the ensuuite right before bedtime, how irritating" I thought and made a mental note to speak to DS about being more considerate. Then, I hear all this moaning and complaining coming from the landing where dp has gone off on one about the state of the main bathroom (which I hadn't been in remember). Apparently ds had taken a shit in there, not flushed it and left it in s state. Ffs I think and make another mental note to go ape at him in the morning as he is old enough to know better. With that, dP bursts into the bedroom and launches into a full scale verbal attack on me, saying I'd ignored it and should have sorted it myself. I told him I hadn't been in there and he retorts that as usual, I'd walked past a bathroom which was obviously in a state because I couldn't be arsed. He tells me he's not a fucking mug and things need to change as he's sick of me and my "fucking posse" being selfish and lazy and expecting him to be a "fucking mug". 
I was taken aback by all this because I honestly hadn't done anything wrong! I hadn't noticed it was in a state as I assumed the smell was coming from the ensuuite (especially as the window was open) but he wouldn't stop attacking me. I chose not to argue back (speechless more like!) and said he should just have spoken to me, not laid into me full force. He refused to back down so I just said goodnight to him. A few minutes later I went to hug him and he said he was far too angry with me and would have to go without a hug he called me lazy and said he was sick of me. I was really upset, we'd gone upstairs fine and he just turned on me like that. Fucking lazy after I'd done the shopping and cooked his tea after been at work all day and then refusing to hug me goodnight?? And after last nights episode I'm sick to death of being his verbal punch bag! Actually quite upset still, could barely sleep all night, 4.30 am and I'm sat posting about it on mumsnet because I can't get it out of my head. I'm exhausted :-(
