Hi Bears....I think buzzard just wanted you to see, in a blunt way, what you are doing.
Its not about the phone, its about him and his behaviour toward you. I dont doubt he is OCD, however, I feel that perhaps he has intentionally or not, used his OCD as a front for being a controlling arse.
As hard as it is, you need to stand up for yourself...its only a phone. Not the end of the world. As far as you being allowed to do less and less in your house? Its your house as much as hi. Do what you bloody well please. The OCD is his issue, that he is being medicated for. He recognises this, therefore, should be making an effort to try and not let it impact on your life. I have no experience with OCD, so may be way off track.
You are NOT careless or incapable. You have been ground down by a man who feels the need to control you. If he cannot see that his condition is affecting your relationship so much, he needs more help.
You DO NOT need counselling he does.
Im afraid I am more on the side of him being a controlling bully who is using his OCD as an excuse, than the OCD is out of control.
Take a deep breath, its not worth it, his impending reaction is out of context. I would take some time to decide if you want a future with this man.
How is his reactions? Are they violent? Aggressive? Passive aggressive?
