I think my girlfriend is being unreasonable
Is it because she's having a bad day?
No, she's always unreasonable.
I mean if she's always unreasonable to you, maybe you should consider having a serious discussion together. You'll both be happier that way.
I told her she's always unreasonable. I think I'm making the right choice.
If the two of you have talked about the future of your relationship and you both feel like the other person is being unreasonable, it may be time to discuss the benefits of the relationship and if they are strong enough to hold you together.
