advice

I'm a college student and have pretty good grades! I met this guy at school and I'm pretty sure he's into me we talk everyday and we hang out too. He has this weird relationship with another girl and in it really sure if they were dating before and are still friends all I know is that she doesn't really like me and I don't know if I should be getting involved in a situation like this! I really like this guy but I'm not sure if it's worth the headache!
