A lover's valentine

Sweetheart of mine,
A valentine,
In duty bound, I send thee,
And wish that joy,
Free from alloy,
May evermore attend thee.

Near, or apart,
Still may thy heart
To mine in friendship nestle;
For strong and free,
In love for thee,
'Gainst countless foes I'd wrestle.

Since I am thine,
Pray do be mine,
My heart prompts me to ask thee;
Thy charming face,
And matchless grace,
I own have quite possessed me.
