My boyfriend and i see each other pretty much 24/7 and yet we never fight..normal?

We've been living together for two months now officially but I've been practically living with him for the past seven-eight months. We also work together on the same shift and see each other quite a bit there including taking all our breaks together. Somehow we just get along without trouble. I get slightly annoyed about somethings and weve started talking about it (I struggle with explaining my feelings) but we never fight about it and things just keep getting better.. i have moments where i freak out just because I have slight commitment issues but I know I want to be with him.
