well I am quite busy with my studies but nice to see you're still doing well Glenn ^^
As for the sentence, it seems to fit in the context (love and stuff >_<) but still the second part seems weird...
I first had something like:
"Because we managed to trust each other, there's now an easy feeling that everyone's longing for"
However the part "信じ合える" made it kinda hard for me to find a (conventional?) meaning.
if it can help you, here's the second sentence
一人は嫌だから そばにいてね 見慣れた街並 いつもの景色で
although I am not quite sure of the meaning of 街並
(Dang that's why I hate translating songs^^')
