Since he has seen the ghost, he has "put an antic disposition on", which is to say that he is acting crazy. Part of acting crazy is failing to dress oneself properly.
But why does he visit Ophelia in her private room in the first place? One suggestion is that he is seriously considering her as a potential ally in his revenge plans. That is why he "falls to such perusal of [her] face as he would draw it." He is looking hard at Ophelia, but what he sees persuades him that she cannot be trusted with his confidence. She is too weak, too easily dominated, and too simpleminded.
Ophelia is hamlets love interest.
Ophelia
Ophelia commits suicide by drowning herself in a lake.
Hamlet Sr. was married to Gertrude. Hamlet Jr. did not marry although he did love Ophelia.
Hamlet was her boyfriend. Polonius was her father. Laertes was her brother. Claudius was her father's employer and her boyfriend's father. Gertrude seems to have been a bit of a surrogate mother to Ophelia.
Polonius is a character, not a theme. And what tells us about the characters in the play is 1. What they do, 2. What they say about themselves and 3. What others say about them, in that order.
No. Hamlet is responsible for his own behavior, of saying unkind things to Ophelia and misleading her, but he isn't responsible for her climbing that tree.

Ophelia belongs to many people. Ophelia is when a person can not think independently.
