Relationship???

What is a couple? A wedded couple is easier to describe, but what is boyfriend-girlfriend? If I like an adam and he likes me too, we spend some times together, we communicate in a more intensive and intimate way than with other friends, we kiss and a bit more (ok…it's up to you guys, can be a bit and lots), I get jealous when a girl approaches him, the way he does, but we never say love, does it mean this adam and I are boyfriend-girlfriend? Yes, the L word is seen as a sacred word, unspoken one. It's a death penalty. No no, you don't want to say it. The way this adam and eve refuse to say the L word to avoid the future hurt. So, is he a lover or a fuckbuddy?
