Mario Winans - I Dont Want To Know Chords & Tabs

this song is damn cool not really got the riff on here and i figured it out the other
day when i was messing around so here u go. I did it around the 12th fret on the B
string but if you so wish you can just move the key about. 
[ Tab from: https://www.guitartabs.cc/tabs/m/mario_winans/i_dont_want_to_know_tab.html ]
E|--------------|-----------|-----------|-----------|
B|--12-10-8-7-8-|---8-7h8-7-|-8-7---7-8-|---8-10-10-|
G|--------------|-9---------|-----9-----|-9~--------|
D|--------------|-----------|-----------|-----------|
A|--------------|-----------|-----------|-----------|
E|--------------|-----------|-----------|-----------|

Then just repeat it pretty much all the way through the song!
Simple as that any corrections just tell me plz.
