Knowing when someone loves you?

I'm going with basically what Stop Sign, Meia and Crash said.

Cherish what you have now, have fun with it while you have it. Keep in mind that you did your best to keep the better memories than the bitterness that would have risen had you focused too much on his commitment level. You never know, he might change his mind.

Sometimes environmental/personal/circumstantial changes can do wonders or horrific strains on the relationship. You're still young enough that you should focus on yourself more, Dee. Relying on a relationship to define your persona can come way, way later.

Jam it back in, in the dark.
