Ever like anybody even though you know you shouldn't?

I can't ignore it; i am attracted to this guy even though i know i shouldn't be. We could not be more of opposites. He is a huge druggie, skips school constantly, and is a major bad *** to all the teachers. However, we talk constantly about deep and meaningful things and really open up to each other about everything. This isn't even the typical girl likes bad guy thing, because its like everyone i know or talk to is afraid of him or don't understand him but they don't even know him or try to know him. And i don't even care what other people think about him, that's how much i like him. should i pursue my attraction or ignore it? if you have ever been in this situation what did you do?
