I transcribed this by ear while listening to the version you can find on mary j. blige
vevo's youtube channel. its not exactly the whole song, as i am going to skip the parts
in which the edge just plays short fills or follows the chord pattern of the song. I'll 
just write the verse and the chorus respective chords. For the full pattern you should
check out the chords for this song which are already on this site and are very good.

First couple of verses go:

    Am                             D                 F
e---------------------------|-----------------|-------------------------------|
B---------------------------|----7------------|-------------------------------|
G-----5-----5h7p5--5h7h5----|----7--5h7p5p7---|-----9-------------9-----------|
D-----7--7--7------7------7-|----7--7---------|-----10-----10h12----10h12p10--|
A---------------------------|-5---------------|-s8------8-------------------8-|
E-s5------------------------|-----------------|-------------------------------|

           G
--|--------------------------|
--|--------------------------|
--|-----12-------------------|
--|-----12--9h10-9h10p9------|
--|-10------10---10------10--|
--|--------------------------|

Then chorus:

It's basically the same bit after the first couple of strokes of the main chord

   C                       Am                    F                   C

e--0--------0----------|--0--------0----------|--1-------0------------|--0-|
B--1----1h3----1h3p1---|--1----1h3----1h3p1---|--1----1h3---1h3p1-----|--1-|
G--0--0--------------0-|--2--2--------------2-|--2--2--------------2--|--0-| ...
D--2-------------------|--2-------------------|--3--------------------|--2-|
A--3-------------------|--0-------------------|--3--------------------|--3-|
E--0-------------------|--0-------------------|--1--------------------|--0-|

and on again just like the first measure

The next verse just features a more rhytmic rendition of the same chord pattern, while
the next chorus features the same chords without the hammer on-pull off parts. The only
notable thing being this:

---------------|  as a transition from C to Am
--1----------1-|
--0----------2-|
--2----------2-|
--3---3-2-0--0-|
---------------|

That's it.

Hope it helped, it's an awesome song. Cheers
