Let me understand. You tend to find yourself writing stories when you write poetry and you consider this bad? Since you can't answer me this moment, i'm going to assume that's what I understood in your comment and try my hand at a rebuttal.
If you have looked in on my posts (I'm new so there isn't much) you will find I very much love storytelling through poetry. I think verse is one of the single most exciting places to tell a story. For the last six years I have labored to produce a "gest". If you don't know what this means (not every poet does), a gest is a long tale of romance and adventure told chiefly in verse. "Çaço, Man of the Morning Star" is (at this writing) 20,000 lines and growing. I don't suggest you turn yourself to writing a great, hoary epic poem that steals your life from you as it wants to be written, but I would like to suggest you go with your strengths. If you have a tendency to write story in verse then do so. Don't let others dictate the style of poetry you write because "it's what everyone else is writing". There is nothing wrong with your writing that can't be fixed with a little training. Your poem, I may have said this, is evocative. The characters experienced very real emotions. And...it told a short (very short) story. In my book, that's a major plus.
If you have the time, look in on Caco, Man of the Morning Star, Canto One. Not everyone can muscle up the time and effort it takes to read me, but you don't necessarily have to read the whole canto. It's simply the only example on the site (there are millions out there) I can point out that is poetry telling a story. Have a look and tell me what you think. And if I'm acting to arrogant let me know, but I have time to help if that's what you're looking for. In fact, I imagine there are loads of mentors here.
Good luck
