Analysis of I Abide and Abide and Better Abide

I abide and abide and better abide,
And after the old proverb, the happy day;
And ever my lady to me doth say,
'Let me alone and I will provide.'
I abide and abide and tarry the tide,
And with abiding speed well ye may.
Thus do I abide I wot alway,
Nother obtaining nor yet denied.
Ay me! this long abiding
Seemeth to me, as who sayeth,
A prolonging of a dying death,
Or a refusing of a desir'd thing.
Much were it better for to be plain
Than to say 'abide' and yet shall not obtain.
