OP, you wrote: "I object to being told off about high bill like im a naughty schoolgirl :( "
This happened to me, very very early on in my last relationship. Like, a few months in. Unfortunately I was pregnant or I would have upped and left, I think. While I still had the spark and the confidence to realize what was happening was totally wrong.
I waited for almost three years for it to get better, it never did. I'll tell you why it probably won't in your situation as well: this kind of attitude in him is just a symptom, not the problem itself. It's a symptom of the kind of dismissive, 'you don't matter' mindset which sadly some men hold about women, and in my humble experience it very rarely goes away. It is very, very ingrained and difficult to shift that condescending, patronizing and downright offensive outlook. Usually, the ONLY way change is achieved is when the man has a kind of lightning bolt epiphany, and decides to change, completely off his own bat, and regardless of whether he has a partner or not or whether his wife agrees to stay with him. Just, he changes because he can see how totally unacceptable and demeaning such behaviour and attitudes are, and develops a horror and revulsion for his way of being - really WANTS to change, in other words. And most aren't like that/don't have that sudden insight, don't want to change.
So, by all means have 'the little chat', he may well get defensive and/or uncomprehending when he realizes you are trying to assert yourself and take an equal role in all aspects of your partnership - although frankly partnership isn't the best word to use really in this situation, because partners implies some equality and you aren't like that from the sound of it.
Talk to him, tell him - don't ask him, tell him - how you want things to be from now on. But I'm afraid it's likely he picked you or liked you in the first place because you're the nice, unassuming type who didn't think to complain when he didn't allow you access to your own phone bills or indeed any bills, and you may now be so ground down that you'll have trouble realizing what a tosser he's being, and that you should be wary and even consider getting out.
I hope you do realize, anyway. Because he sounds like a nightmare frankly, and in case it's not already apparent, I think his behaviour is way out of line and totally unreasonable.
Good luck :)
