<human>: Can you give me the gist of the text in a nutshell?

I feel awkward asking this, especially since I'm a tall, muscly guy. I've been dating a girl for a little over a year and it's starting to get weird. She's always been passive aggressive, lately she's been aggressive, but only verbally.

Examples: If we are watching tv and an attractive guy comes on she'll talk about how attractive he is and how she wants to sleep with him. She talks more about other guys than she does about me...to me. I train and compete in kickboxing. If I make any mistake she's quick to make references to me having brain damage. She makes fun of me a lot, but then she'll pull back like she was just joking. She gives me a lot of "you're lucky you're good looking"  and when I finally asked her what that means she just kinda huffed and went back to her laptop. 

Can't this just be a jealousy thing? like she's not trying to hurt me, but rather trying to get attention? I really like this girl.
<bot>: My girlfriend has been really passive aggressive lately and purposefully showing interest in other guys. Is she hurting me on purpose or just trying to get attention because she feels neglected?
