Samuel Daniel Sonnet

I just read If this be love, to draw a weary breath the the other day and was kind of confused. I figured it was about him loving a woman who not only rejects his love but also shows no remorse towards hurting his feelings. But I feel like I’ve only scratched the surface of this poem and im hoping someone out there can enlighten me.

If this be love, to draw a weary breath,
Paint on floods, till the shore, cry to th'air,
With downward looks still reading on the earth,
The sad memorials of my love's despair.
If this be love, to war against my soul,
Lie down to wail, rise up to sigh and grieve me,
The never-resting stone of care to roll,
Still to complain my griefs, and none relieve me.
If this be love, to clothe me with dark thoughts,
Haunting untrodden paths to wail apart,
My pleasures horror, music tragic notes,
Tears in my eyes, and sorrow at my heart.
If this be love, to live a living death,
O then love I and draw this weary breath.

any ideas?

I think hes talking more along the lines of love really hurts like when he says If this be love, to war against my soul, Lie down to wail, rise up to sigh and grieve me, The never-resting stone of care to roll, Still to complain my griefs, and none relieve me. If this be love, to clothe me with dark thoughts, Haunting untrodden paths to wail apart, My pleasures horror, music tragic notes, Tears in my eyes, and sorrow at my heart. If this be love, to live a living death, O then love I and draw this weary breath. hes basically saying if this is love then just kill me now (blunt interpratation) but thats just my interpratation
