Hey everyone I'm jason, I'm a junior in high school.
I really like this girl and I think she likes me too
We text a lot and I get her out of class at least once a week and we just walk around school and talk. My brother has a class with her and she talks about me with him. I don't know where to go with this, any help from anyone will be helpful.
Thank you

Let her know you'd be interested if she were ever free. Don't lead her into cheating, don't let yourself take second string to any other guy.

Meanwhile, continue being a friend. Be careful, it's really easy for you two to be "bad" the way you're acting. Please be the good guy. What you do now will have a long-term impact on what you find acceptable in relationships later in life. Don't let yourself become OK with being a cheater or underhanded... be the good guy.

If she's got a boyfriend and likes him and he likes her back, you should just back off.
Put yourself in her bf's shoes.
How would you feel if your girlfriend was flirting around with some other guy?
