Why Does My Girlfriend Want To Argue All The Time?

Maybe she wants attention or maybe she just wants to talk, if so then sit down and listen,try not to argue or raise your voice because it might make her seem frustrated when she wants you to listen to her oh and try to understand the problem (if there is one) through her eyes and perspective

Oh yeah,that's how they emote.Especially if they're kinda young and immature.

It's usually conflicting when expectation exceeds reality

What does she argue about?

She probably needs more attention or maybe she is just trying to tell you she does not like you anymore or maybe it's that time of the month for her....Hard to say. Just remember life is short.

Either she's looking for your attention in an arguing ways or trying to pick a point with you so she can break off .
