<human>: Can you provide a brief overview of the text?

(This is one of the first times I've ever posted on Reddit so sorry if I screw anything up)

Alright, so I'm a freshman in high school, and this guy is a junior who's about to turn 18. And he has a child. 

I've always done pretty well in school, I've always gotten all A's and I never really get in trouble, I'm a good kid usually. This guy is the type to go to a lot of parties, somehow makes just about every teacher in the school hate him, definitely not a great influence on me. Of course he is trying to do a bit better this year because he says that he wants  to get his high school diploma, but I'm still not sure what to do. 

He is in my biology class and sits next to me but there isn't anything I can do about that thanks to assigned seating, so I can't just avoid him. A few days ago he asked for my number, and I must've not been thinking at all because I ended up giving it to him. We have been texting though and he is actually really cool (which I decided after a 4 hour long conversation about Pokemon and Lord of the Rings) and I know that we like each other but I don't think I'm going to go out with him because I'm sure it'd be way more trouble than it's worth. Plus age gap and ya know, the child. 

Anyway, I have no idea what to do. I like him so I at least want to be friends but I know he likes me back and now I don't really trust myself to say no if he does ask me out.
<bot>: I somehow got myself involved with a guy who I know is a bad influence but I have no idea what I should do about it
