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

So I've known this girl for 2 years now, met her back in Middle School. Recently, we've been getting into some what of a serious romantic relationship. She came from a family that were both drug addicts, but she doesn't have troubles with it her self. Though, her dad has been involved in some heavy things, and also I was aware he has done things that she has not forgotten about. This guy has 2 tear tattoos, if you know what that means, the guy is serious. Anyways, I've had my share of introducing myself to family, making good impressions. She was brought into another family when she was in 7th grade, and I made great impressions on all of them with them liking me into their family and has since stayed with them. Though she still has contact with her family, who I still have never met except her siblings (which also like me). My question is to those of Reddit, this guy isn't the average Joe. He's scared away a few people before, but I'm sure as hell not going to be scared from it. Can I get some help, making sure I don't mess this one impression up. Her dad seems to be a tough guy, just want to know if there are anything I should take cautiously. Thanks
<bot>: Girl I have known for 2 years, getting into a relationship. Her dad is a tough guy with a drug / violent past, how to make a reasonable good impression.
