is it normal ...

[Lopsidale]

To argue everyday? I can't remember the last day we didn't have an argument and it's really starting to drag me down

Nope.

Thats what people who dislike each other would do.

No.

My GF and I haven't had a cross word in over 4 years together.
If we have a difference of opinion we talk about it and reach a compromise were both happy with.

I'd suggest you need to step away for a while and think what is keeping you with someone you're evidently unhappy with

No it is not normal at all.

What are you both arguing about?.
