Seeking Advice on Marriage Readiness and Living Arrangements with Fianc

Assalamu Alaikum Sheikh, I am seeking your advice regarding my upcoming marriage. My fiancé’s parents are both 74 years old, but his mother is still very capable — she works as a social worker caring for children, and his father is also working. My fiancé is refusing to live alone with me after marriage, saying his parents are old and that he is their only son. I agreed to live in his parents’ house so that in the future he would not blame me for keeping him away from them. His mother has offered me her old gold as my mehr. I did not ask for any mehr, but she insisted, so I agreed for it to be written as such since my fiancé has no job yet after graduating from university. Due to him having a car now, he goes out all the time with his friends to their apartments and elsewhere, and he often returns home very late at night, sometimes after 2 a.m. He says it is acceptable because he is a man and can do as he wishes in Islam, but that women cannot. Our marriage is due in two months, but he has not made any preparations. He also wanted to extend the engagement for another year, saying he is not ready for marriage because he does not have a job. His father is currently staying in the bedroom I am supposed to move into, but he has not moved to the other room. My wedding was first planned for April, then changed to September, and then changed again. Now his mother says her son is too young and should not have gotten engaged. She also mentioned his father might go to Pakistan in October. I feel confused and unsettled about these changes and his behaviour. Sheikh, what should I do in this situation? JazakAllahu Khairan.
