Been together just over 3 years. Even from the beginning he was difficult to work out, played mind games, led me on and messed me about but somehow we survived. Last year was our first year living together and I learnt that he was confrontational and highly argumentative. Unpredictable moods and unfair expectations. ("I want you to work/I don't want you to work" ) etc. I learnt I couldn't win no matter what I did. It was an awful year, weekly arguments over nothing but he'd drag them on far longer than need be despite my pleas of "kissing and making up". Eventually I could cope with it no longer, his animated piss taking, his impressions of me, his sarcasm etc and I told him we were not working out. He accepted part blame and promised he would stop being argumentative and confrontational.
He did stop and we had a nice few months but it's started up again. Past two weeks he's been in one. It makes me paranoid and I end up asking what's wrong, he snaps saying it's me asking that which puts him in a mood. Last night perfect example of how he used to be ... He asked me what the plans were for the following week. I didn't know if he meant work, school, hobbies or what so asked what he meant. He snapped "oh got fucks sake, I just wanted to know what everyone was upto next week but you don't want to tell me got some reason! Forget it!". This carried on long after I explained my shifts and any appointments for the week he continued to say I didn't want to tell him anything.
Sunday morning we had a very rare lie in together with no kids in house. I asked him to stroke my boob. He half heartedly poked around a bit then stopped so I said "you could at least act as if you enjoy it". Well that was it, he shouted that I did his "fucking head in", decided to inform me that he is not a dog and will not. "Perform" just because I demand it (ffs a woman asks her man to touch her, is that really an awful thing to do??). He went on and on. I said "ok come on, let's not argue, we don't get many opportunities to lie in bed together, can we have a kiss and cuddle?" So he snapped "nah. I'll see how your mood is later tonight and make a decision then" 
he was basically saying he'll judge my behaviour later and decide whether I deserve his attention if not. That's fucking awful.
I'm just sick of not knowing where I stand with him. One minute he's lovely, next minute he's horrible. He also denies saying stuff and tries to make out that I'm not listening. Last night he said he was working late Thursday and that he'd told me a million times and he'd said that all along and I just don't listen. Within the same conversation he said was working late Tuesday and that he's said that all along snd had never said he'd be late Thursday at all 
sick to death of it all.
