Do you think Lady Macbeth is constant in her love for Macbeth?

Before determining wether or not Lady Macbeth was constant
in her love for Macbeth, you first have to determine the nature of her love to begin
with. Lady Macbeth, though it is possible she may have felt some sort of romantic
passion for him at some point in their relationship, is principally concerned with
power. Every action she takes is to preserve, enhance, and expand Macbeth’s power and by
proxy her own influence through his affluence (until, of course, her eventual demise).
At Lady Macbeth’s point of demise, she is incapable of love or any real emotion at all
that extends beyond the desperation of her predicament. So, did Lady Macbeth remain
constant? If we accept that she never loved him to begin with, then yes -it remained at
a constant absence. If we consider what may have happened before the beginning of Act I,
perhaps -but throughout the duration of the comprehensive play the only real affection
she affords is to power.
