OMG all of this too! Why are all these men so similar! 😆
Apart from the theatrical sneezes, I also get him saying 'oh dear...' or 'ha ha ha' when he's looking at his phone (or even when he's just sitting there doing nothing.) He wants me to say 'oh what is it, PLEASE do tell me!' I have stopped asking because I get so annoyed by it. ALSO, he asks me 'are you going out up town tomorrow?' I say 'not sure, why...?' 'Oh, no reason' he says. Why the fuck did you ask me then?! 
The length of time he spends in the fucking bathroom. Literally, when he goes in there for a shower and to wash his hair (and sometimes a shit before he does this,) he is there for nearly an HOUR some days. Most days it's at least 40 minutes. He says to me 'do you need the bathroom?' (like for a wee) before he goes in, and I say 'no.' 45-50 minutes later I need a wee and knock on the door and say 'have you finished in there yet!?' He says 'I thought you didn't need the bathroom!' I said, I didn't need it nearly an HOUR ago when you first came in here. What the fuck are these men doing in there?
Also, yes, chatting shit about stuff I am not interested in. And it's particularly annoying when HE is watching one of HIS (shitty) programmes and I am trying to read or look at the internet, and he gives me a running commentary! I have said 'I AM NOT WATCHING IT, I AM NOT INTERESTED!' a number of times, and he still does it. He says with a forlorn look 'well I am interested!' I am like 'so?' It's like he expects me to stop everything I'm doing to listen to his drivel. So I just 100% flat out ignore him now and carry on with what I'm doing. He still mutters away about what he's watching though, and laughs out loud at stuff that isn't even funny and so on, so sometimes I have taken to sticking my headphones on/in my ears and putting music on so I don't have to listen to him...
And the hanging around in the kitchen when I am busy/washing up/cleaning/preparing dinner etc etc!
He often just stands there at the door watching me! I'm like 'yeah?' and I look at him with a 'whaddya want?' look on my face. 'I've just come for a chat' he says, and he starts wandering around our (fairly small) kitchen. I say 'we can CHAT over dinner, right now I'm busy and you're in the way - (10 X 12 foot kitchen so not huge!) He says 'oh, I didn't know that I was SO FAT, and SOOOO HUGE that I can't fit in the kitchen at the same time as you!'
He can't seem to comprehend that it's not his 'size' it's the fact that he is there, hanging around like a fart, and if he stands ANYwhere in the kitchen, he is in my way for at least half the bloody time he's in there. I am at the sink, at the fridge, at the wall cupboards, at the floor cupboards, at the cooker, at the worktop, and then back again and again for the 30 minutes or so I am doing dinner. He is just a bloody nuisance when he's in there. Last time he did it (he does it about once a week!) I said 'if you wanna be in the kitchen, knock yourself out! Stay in here and cook dinner, and I will sit in front of the TV!' He sloped off in a sulk. Pillock! 😆
