Sonnet 42

by William ShakespeareThat thou hast her tis not all grief,And yet it may be said I loved her dearly,That she hath thee is my wailing chief,A loss in love touches me more nearly.Loving offenders thus I will s’cuse ye,Thou dost love her, because thou know’st I love,And forsaken so doth she abuse me,Suff’ring my friend for my sake to approve.If I lose thee, my loss is my love’s gain,And losing her, my friend hath found that loss,Both find each other, and I lose both twain,And both for my sake lay on me this cross,But here’s the joy, my friend and I are one,Sweet flattery, then she loves but me alone.
