So basically, we have a decent marriage - it's had its ups and downs over the 20+ years we have been together, but we get on pretty well.
But DH is grating on me with a few certain things.
Sometimes, when I am doing bit of housework, (if he is there,) he watches me and smiles, with his head titled. When I say 'what are you smiling at?' he says, 'you just look so cute doing the housework, just tootling around with the duster. Makes me proud of my little wifey seeing you look after our house.'
(We are both in our 40's, with grown kids, and we both work - me 24 hours a week, him 35, flexi time.)
Then I get occasions when we are talking, whilst having a coffee in starbucks or the like, and I start talking about something serious - terrorism, or climate change, or endangered animals. When I am in full swing, he just starts smiling at me, and tilts his head (again!) and sighs gently... I say 'WHAT?!' He says 'you just look so cute today!' 
I am thinking 'FOR FUCK'S SAKE! I was talking about something serious and giving my views and opinions, and he is basically saying what a fucking fluffy rabbit I am.
I have said to him before, 'what the hell, I was in the middle of talking then.' And he gives the fucking head-tilt and a simpering smile, and then sighs, and says 'awww but you're so cute.'
Also when I am eating, (sometimes, ) he will just look at me and say I look 'cute' when I am eating!
I feel quite self conscious of people watching me eating, and it makes me cringe when he says this!
Then there are occasions - at least once or twice weekly, when I will be doing the washing up, (or ironing,) and he will suddenly grab me from behind, and hug me, or nuzzle my neck, or grab my boobs. (Sometimes all at the same time!)
And there are other times when I am say, typing on my laptop, and he will just suddenly appear and kiss me on the head, or pat me on the head, and say 'Love you!' AND there are times when I am trying to walk out of the room and he stops me and says 'not til I get a kiss,' and literally grabs me and pushes his face against mine, (like 2 inches away,) and just stares into my eyes, saying 'I love yooooo.'
And other times, he just kneels down by the armchair I am sitting on, and puts his face right up close to mine and looks doe-eyed at me, and says 'LOVE you!'
I feel like a bit of a cow, but I am so fucked off with this obsessively touchy feely behaviour. Through his 20s and 30s he wasn't very affectionate and touchy feely but I wasn't that bothered tbh as I am not either. (Only with the kids and the cats!) I do not know what's driving this, and I have said a few times that I think it's a bit much, and he has got huffy and said 'can I not even be affectionate with my own wife?!'
I do love him and care about him, and most of the time he is actually OK, and he is a good dad, a good husband, and a good provider, but this side of him is pissing me right off!
I suppose in some ways, I should be grateful I have a man who is affectionate, but he really does grate on me at times. On the occasions I do say it's annoying me, he comes out with the usual line... ' what's wrong with wanting to be affectionate with my own WIFE? ' And 'you never USED to complain about me grabbing you etc.'
Whenever he does it now (which is quite often,) I find myself feeling more irritated each time. And when he gropes me from behind, I feel myself tense up.
Am I being a bitch? Or would all this piss you off too?! It's like, I know I am his 'wife,' but I am not a fucking toy for him to play with, and I would like to air my views on serious issues, without him grinning at me and saying I am a cute fucking fluffy kitten! 
(We have a reasonably healthy and satisfactory sex life by the way. And always have had...)
