Hello TheLad, welcome to English Forums!
No, I'm not your English teacher, so you're ok.
The poem was first published in 1842 (not 1942), and he met EBB in 1844. So there's no connection.
There's a page on Wikipedia with the historical background to the poem. You can find it here:

Good luck on Friday,
