could be

[tectak]

I am obsessing a love You may only just get away with this missuse of the "obsessing" word on the grounds that it may be used this way over the pond. Strictly you are "obsessing over" or "obsessing about" is correct.
that thrives on war.

I’ve abandoned the joy of
clustered Rhododendrons;
their beauty bores me. Interesting dichotomy here. You translocate and juxtapose the feeling of joy with boredom rather than misery, joy's natural antithesis. I think this weakens the intent, heart." ...their beauty saddens/depresses/deflates/grieves me"...? Your poem.

I am weaving through heaven
without a tether.
Tangled on a string of stars,
losing our connection. You are so far - This stanza could be better punctuated. It is a single and self contained thought. Keep the elemenrs together. Comma after tether then semicolon after stars. Last line is safe however which way you go. There is a poignancy in "You are so far" which is pure distilled spirit , dripping away through the useless leaking dash. What IS it for?

A thousand miles of oceans lie No. I do not see why "oceans". ..hold on, bear with me
below this abyss of could be. A thousand miles of ocean lies beyond the Abyss of Could Be.

Hi heart,
I don't want to like this because it is trite. The expressed thought is never in any danger of developing into anything other than an Exocet heading for the last line, programmed and committed in a technically cold and precise fashion....yet the very predictabilty of it makes it comfortingly familiar. It is like someone standing in front of me agreeing with everything I say.That may be skill...I do not know... but in spite of it and me, I find I DO like it
Best,
tectak
