Met my boyfriend when we were 16, but we didn't start dating before we were 17, because we were friends first. 2 years later and things are better than ever. We both started university and I've moved out of my parent's house. We just went through so much of our personal development together, and there's no one that knows me better than he knows me. I never want to loose him, but there's this little voice in my head saying "stop being young and stupid, all good things end". So am I being an idiot for thinking this could last forever?
