being too comfortable?

I think things might be getting to comfortable where things are at.  Britton and I fight/argue/disagree all the time.  We can't even get through a civil conversation anymore.  I don't think we should break up, but things definitely need to change.  I hate arguing with him all the time and I'm probably mostly to blame, but I don't think I should be the one to change.  The things that I want him to do, I've wanted him to do since the beginning, which I've adapted to somewhat, but when I ask for help to find something, all I want is a little help.
