How Was I To Know Poem by Lesego Tsiu

How was i to know that moving on would leave a pain in ur heart?
How was i to know that parting ways with you will make you cry all night?
How was i to know that leavin' you would be a big problem for you?
How was i to know that i was a part of you that never had to leave?
How was i to know that you and i never had to break up?
How was i to know that persuing my happiness would be creating a big pain for you?
How was i to know that you were the one that i never had to leave?
