Good advice for people just entering a relationship. Saying "I love you" automatically attaches some kind of commitment to that person. If you really love me, how can you go and dump me four weeks later without even an attempt at communication about any problems you might have with the relationship?

I think in particular that lots of high school relationships are this pointless. Before you say "I love you" you should make sure that you're in a meaningful relationship. Sorry if this sounds bitter - my first girlfriend in high school didn't communicate with me well and I assumed that since she told me she "loved" me everything was well. She dumped me 6 weeks later and I still don't know why.
