>>1 Poor of you.
Getting into a relationship with someone you seem to like, while it doesn't happens to lots of other people.
Life is so cruel toward you.
IMO, just do the way you'd like. And stay romantic, pay attention not to harm your lover too much. And stay safe : avoid public transportation and dangerous places at night when you hang out, wear a condom, and abide to all this common sense rules and to the laws.
Assuming you're in high-school, they outcome of your relationship is unlikely to matter.
