When many things in the world are not as perfect as expected (this "many things" depend on your boyfriend's mood at that time, but I don't know what it means), but I can also find you in the distant ups and downs.
Personally, your boyfriend may have gained something from your cold war. Life is full of ups and downs, not smooth sailing. No one or thing is perfect (this is the reality), but it is very gratifying to meet you in this life.
Personal feelings, for reference.
Or, as upstairs said, I just like this song, and I feel very much after listening to it, or I like this lyric very much (maybe he doesn't understand this sentence very well himself, but he just likes it very much).
