<human>: Provide a brief overview of the text.

Backstory: my girlfriend use to be heavy into marijuana use but now is clean. I still smoke on occasion.

Also: this girl really isn't my girlfriend but I don't know what else to call her.

I met my girlfriend at the beginning of the school year (we are both seniors in high school) and we hit it off very well. We talked for about a week and then we went on a first date which went well. We became partners on a biology project and I went to her house to do it. 

She warned me that her parents were very keen on good first impressions which made me very nervous to meet them. Meeting her parents did not go well to say the least. I tend to freeze up a bit when i get nervous and i did not make a good first impression. Eventually i went back again to complete the project and i feel that i made a better effort to get to know her parents but she told me they still did not like me and that i reminded them of her ex-boyfriend who they hate.

This wouldn't be to big of a deal because first impressions are changeable. However one night we were texting about how she used to be heavy into marijuana use and she doesn't want to be with someone who smokes.I told her i would  (and have) stopped smoking for her. Apparently one night though her dad took her phone and read the messages about me smoking, which her then told her mom about.

Her mom, who already didn't like me from meeting me, now found out that i smoked weed and has forbidden her daughter to see me, and even drug tested her daughter after she found out that we were hanging out after school together.

Should i just give up on this relationship or should i go to her house and talk to her parents about how I've given up marijuana and that their daughter is more important to me than getting high.

My girlfriend does not want me to talk to her parents but I feel like that is the only way to even begin to get her parents to like me.

Thank you for any help and sorry if the formatting is shitty this is my first post.
<bot>: after making a shitty first impression girlfriend's parents found out I used to smoke. Do I meet with them about it or give up?
