Probate Question (next Of Kin) - Maine/florida

Hello!

Location: Maine and Florida.

My 79 y.o. father passed leaving me nothing in his will, and everything to his former girlfriend. She is also the executor of the will.

I am his only child, I am an adult and next of kin.

A sheriff's deputy came to my home in Maine and notified me of his death. The deputy put me in contact with a victim's advocate in Florida, where my father died of natural causes, alone, at home.

The victim's advocate gave me the name of the funeral home and recommended I request copies of the death certificate and provide them to social security. I have not seen my father in 12 years.

That victim's advocate gave me the name of the funeral home where my father will be cremated. I signed the paperwork permitting them to cremate him and print off death certificates. The funeral home advised that he had prepaid for an urn, cremation, medical examiners' fee and death certificates, so all I had to do was agree to sign the paperwork.

I was estranged from my father but would like his ashes, which is why I managed the funeral home arrangements. He wished for no services.

I made the funeral home aware that the former girlfriend's name is not to be put on the order of disposition. My major concern being she would take the urn. Apparently, she called the funeral home multiple times requesting copies of death certificates (he died yesterday) even though I had told her I was going to do that per recommendation of the police.

The staff told her she cannot have access to those but she can request them through the state of Florida.

She's big mad because now she can't get [a certificate] "to the bank fast enough" (her words, not mine).

Anyway, legally, is there anything else I'm supposed to do or know as next of kin? I've never had a parent die, have no siblings and very few family to guide me in navigating this, any guidance greatly appreciated!
