I personally love this. Its a great poem, great job. The only thing I would suggest is where it says :Why did our relationship fail?
After all we ever done, it would sound better if it was:After all that has been done. But I still like it, you did a nice job! And yeah I kind of know the feeling of this poem it sucks. I hope things get better! You know there is always other people out there and it'll be hard to get over it, but itll happen in time. Well I hope the best for you and that things get better!
