Puzzles: a thought

I was having a thought about you, what was I thinking about,

Weaving in and out th’ day, a dream, not really thinking

About you, purposeless branches, breathes in,

Out, it’s way to hang itself around something to do with you

But what that is I’ve thought about, day in, out, a love

Of which, I don’t really know the purpose to, that

Each day just breathes in affinities,

With no purpose but themselves, supporting thought,

Now seems more than I, in thought of you, life seems just

Dreaming of love, I just thought you dreamt affinities, too
