The GF started smoking a ton of weed today because I didn't pay attention to her for 5 waking hours and she isn't knowledgeable or cultured on anything, she only likes really bad movies, podcasts with whores and shitty pop music. She also can't go more than 10 minutes without looking at instagram and youtube shorts and argues daily when she gets too comfortable with me. She is obsessed with becoming famous even though she does nothing serious towards that end. Her main pasttime other than these things is sitting there with me expecting me to entertain her or sitting there in a shitty mood and expecting me to make her feel better even though it's impossible. I feel like I learn way less and go out less because I have to talk to her all the time (we live apart and she visits me every so often for a few weeks at a time). She recently failed out of medical school immediately after getting in because she is retarded and has a 3 second attention span, and because of that she won't even be able to see me in person when we thought she would be able to.

Should I get over her and dump her despite being attached to her or is there no point because all women are like this, so if I get another gf it will just be more of the same?
