Been dating this girl for more than 6 months. I am starting to think that she is aggressive.

Sometimes my girl acts or says dumb things like if she was super cleve, I laugh at her. She gets frustrated and has an aggressive tone. I keep laughing and not giving her attention. Then she says she is sorry blah blah blah.

Yesterday, I came to her house I was a bit tipsy since I was hanging out with the boys. She bought me some chocolate and I started doing stupid shit with the paper of the chocolate. She told me to pick it up on a serious tone, I did and I decided to go. Put on my clothes and she was holding me and not letting me go. She got aggressive. I went to my house straight away. She got really frustrated cause she says I’m avoiding her and that I prefer to hang out with my friends. I’m not seeing her often and she is pissed off that I was leaving her house with just 20 mins of seeing each other.

What is the reason of her behaviour? I believe I’m holding frame but maybe she needs more comfort?
