Hamlet is mourning his father's death while others are celebrating the remarriage of Gertrude. In his soliloquy, he states, "oh, that this too, too sullied flesh would melt, thaw, and resolve itself into a dew," Hamlet wishes to disappear rather than witnessing the happiness of the court about the marriage. He is confused and feels betrayed as to why she married his father's uncle. He said, "frailty, thy name is woman!" woman referring to his mother. Now, his view on women is weak and disgusting as his mother married Claudius because of incest and which her mourning never lasted for old Hamlet. This led him to be furious and depressed that he views the world with cruelty. Hamlet's struggles whether "to be or not to be".
I agree with Frizia, Hamlet is at a point where he is confused because he can't understand how someone can remarry so soon. His mother was crying a lot at his dads funeral, but all of a sudden she marries. Hamlet states in Act 1 Scene 2 "I know not "seems." 'Tis not alone my inky clothes, good mother, Nor customary suits of solemn black, Nor windy suspiration of forced breath, No, nor the fruitful river in the eye, Nor the dejected havior of visage" Hamlet does not know what to feel because is in shock because he doesn't understand how his mother could move on so quickly.
Hamlet is going through a tough time because his mom (Gertrude) is remarrying his uncle who is the king (Claudius) now due to his fathers death. In Act 1 Scene 2 it states " These indeed "seem," For they are actions that a man might play." This shows that he is being affected by his mothers remarriage and that she probably was faking her pain when Hamlets Dad passed away. Hamlet is disoriented by the fact that a few months later after his passing she married her husbands brother who was the new king. Hamlet says in Act 1 Scene 2 "But I have that within which passeth show, These but the trappings and the suits of woe." He is also disoriented because his father passed and he can't seem to let him go.
I have to agree with you Luis, very enlightening comment. Providing the insight of hamlet mothers true emotion toward the murder of her husband. And then shortly after coming to find that she's remarrying, and to his uncle. Mind boggling and confusing for the audience, but imagine in Hamlets shoes?
