It is about eternal and unchanging love. The poet begins by stating he should not stand in the way of true love. Love cannot be true if it changes for any reason. Love is suppose to be constant, through any difficulties. In the 6th line, he makes a reference to love and how is like the north star to sailors, "That looks on tempests and is never shaken;/ It is the star to every wandering bark," . Love should not fade with time, but lasts forever. When in says, "Love alters with his brief hours and weeks,/ But bears it out even to the edge of doom" (lines 11-12), Shakespeare is saying that love is timeless and only death can end it.
I believe that this message is true. True love can really endure anything. You can see this all the time especially when you see men and women going over seas to fight for our country. When i was younger i had a friends, whom i fet during football, and our families were very good friends. His father was in the Army Reserves, and he was not called on to many missions. But when i was in 2nd grade, he was summoned to go to Iraq. He spent 3 years over seas. He had 4 boys and his youngest had just been born. This was very hard for their family, and the one thing that kept them going was knowing that the other person loved each other and that they were truely in love. Luckily, he came home with no harm and they are currently living happy, with their family of 6.
