I can't mend it

I can take a little cement and mend our patio
I can fill in all the rough spots so they won't even show
I can mend a roof of shingles with a hammer and some nails
But baby when I try to mend your broken heart I fail
I can't mend it I can't mend it
Your big heartbreak was my mistake but I did not indent it
I lost my head and words were said but that's no cause to end it
Give me the parts to patch your heart I can't mend it

I can hand a shaky table and mend the legs with glue
I can send it down and paint it so you'd think it was new
I can mend a shattered window that a storm has torn apart
But I don't know which way to go to mend your broken heart
I can't mend it...
I can't mend it...
