Mr.Bennet blames himself for Lydia's elopement because he thinks that he has been ignoring his duty as a father and has not been taking proper care of his daughters.
Mr. Bennet is somewhat responsible for Lydia's elopement due to his neglectful parenting and lack of discipline in the household. His indifference towards his daughters' personal development and the moral upbringing contributed to Lydia's reckless behavior. However, Lydia is ultimately responsible for her own actions.

Mr Bennet shoked Mrs Bennet when Mr Collins asked for marrying their daughter. The latter did not accept and Mr Bennet said nothing. In fact he liked her decison. And this made Mrs Bennet angry with him because her aim was to make her daughters marry whoever asks for them.
If Mr. Bennet had been more involved in guiding and supervising his daughters' behavior, he could have prevented the scandal by providing them with better guidance on how to conduct themselves in society. Additionally, if he had taken steps to address Lydia's flirtatious and impulsive behavior earlier on, it might have prevented her elopement with Wickham.
Mr. Bennet had some kind of limitation on his ability to will his estate to his family; Austen says that Mr. Bennet's property may only be inherited by a mal. After Mr. Bennet's death his land will go to Mr. Collins, his closest male relative.
Mrs. Bennet wanted Mr. Bennet to take the family to Brighton.
