Can anyone tell me the meaning of this quote by william shakespeare?

Question

this is the quote:

'Love is not love which alters when it alteration finds. It is an ever fixed mark that looks on tempests and is never shaken. Love alters not with time’s brief hours and weeks, but bears it out even to the edge of doom.'"

Answer 1

'love is not love which alters when it alteration finds'

love is not true if it changes when situation tries to force it to

'it is an ever fixed mark that looks on tempests and is never shaken'

it is a constant, even in the face of adversity or storm (tempest)

'love alters not with time's brief hours and weeks, but bears it out even to the edge of doom'

love doesn't change over time, rather it withstands time to the end
