your piece to be very thoughtful and interesting.
I'm supposing that your main point is that lust and possession
are the parts of love that are dangerous and unwelcome.
I get that. I like the theme and the caution that prevails.

I think that there are too many [so] in this one.
I think that maybe you might change a few of them and still be just fine.

I very much like your title and your poem content. You examine both sides of the topic. in this one line:

But though love can be so painful

It can also be so beautiful (my suggestion is: It can also be sweetly beautiful) to break up the repetition.

punctuation could be beneficial, too. although it is obvious to this reader where the line breaks are. these are my favorite lines:

It can make us feel worthless and empty
And consume us in our sorrow
The dark side of love can be so draining
Until we've no more strength to borrow

good work!

Like this poem. It talks about the side of love no one wants to discuss out loud...the elephant in the room, if you will. I have experienced the dark side of love more then the brighter side and your poem touched on all those emotions. Well done.

I like what you have tried to do with this Clentin, but there are so many ways you could tighten it,
get rid of many of the odd words that break up the rhythm. As a suggestion, ditch the so, ands, and buts. They are not necessary.

It can make us feel worthless and empty
And consume us in our sorrow
The dark side of love can be so draining
Until we've no more strength to borrow

Cat likes this stanza, I would suggest, as an example, you take out the and at the start of the second line, so before draining and write Till for Until.
Good work. Alex
