People sleeping with her husband Zeus
No, Poseidon did not hate Hera, they were sister and brother.
No, but Hera is jealous of Aphrodite's beauty.
It was because Leto had sex with Hera's husband, Zeus, and had gotten pregnant by him.
She hated Aphrodite for flirting with Zeus
Well, I'm not sure, but I thought Hera is from the Greek mythology and Poseidon is from the Roman mythology. however, the Romans copied the Greek gods but gave them another name, Poseidon was the new name for Zeus. Zeus was Hera's wife, so I assume she did not hate him. NO
it enraged her because Zues her husband had Hermes with a woman.
It was mainly Heracles she hated, but she wasn't nice in general so maybe.
There was a rivalry -not 'hate - between Aphrodite, goddess of love, Athena, goddess of wisdom, and Hera, the Queen of the gods; it escalated at the point of the golden apple of Discord.
Depending on the account you read, Athena was either Hera's step-daughter or her sister, and although in the step-daughter account, Hera was very angry at Zeus for having a child without her, the anger was directed at Zeus (or in some accounts his mistress), and not at Athena herself.
First Hera does not hate all people. The reason she didn't like Hercules was because he was the son of Zeus (her husband) and another women.
Hera didn't hate Aeneas, per se. She was upset with Troy, and Aeneas was a Trojan. She sided with the Acheans against Troy because Paris chose to give the Golden Apple to Aphrodite rather than to her.
No, she loves her children. Though Hephaestus, a son she bore alone, had to gain her love due to his appearance and lame mind.
