Why can't I look you in the eyes anymore?

I recently realized that I cannot look you in the eyes anymore while talking. Heck! I cannot even look AT you. I don't know why but I just can't. It some how feel awkward. What happened to being comfortable, being able to talk about anything? Sometimes, I even feel like our conversations are 'forced'.

What phase is this? And is it a good phase or bad? Where is this leading us, most importantly me? I'm the one stuck in this deep shit. You on the other hand are lying in a bed of flowers.....
