where to start?

I don't know where to start. I have been with my partner for 3 & half yrs, and sadly our relationship is going downhill fast. He has mild OCD and high axiety issues; and the way these issues affect him is taking a big toll on me. I think its these diseases that makes him extremely self-centred as well.

I'd say its the anxiety that causes his insomnia. He blames me and my snoring, but really, if it wasnt me keeping awake it would be something else. A flea fart would wake him!! The anxiety also keeps him moving. He can never be still, doesnt know how to relax; he has ants in his pants!!

He doesn't like to see me "idle" or relaxing with my colouring-in (which I have taken up in order to de-stress). He's always coming up with something to keep me moving as much as he is. And whatever he comes up with always, but always, benefits him in some way - hence the self-centred.

The OCD affects him a few ways - none of it debilitating though, thank goodness. He has what I call his "locking rituals", repetitive habits and obsessions with time. If he suggests we are doing such & such at 10am, then it must be at 10am and not a second later!! Earlier if possible, and he'll be ranting and raving at me to hurry, as I am too slow. I hear those words on a daily basis - 'you're so slow'!! He'll have the car idling whilst I'm still brushing my teeth - but its only 3mins to 10. "Hurry up or I'll leave you at home", he yells angrily.

The anxiety over his time-issues, (and other issues) means he is often angry and often explodes over (what I think is) nothing.

Its this explosive anger that is takiing a heavy toll on me. (I have my own anxiety issues, and cannot handle angry loud voices). I find I am constantly "doing things" not to please him, but to try to avoid angry outbursts. I feel I dont get time to myself, as I am always doing something for him; either because he has asked me or beacause I am pre-empting something.

And no surprises here - he doesnt believe he has a problem.

Any suggestions?
