Life as a warrior. Sif and Thor are separated when his father Odin banishes Thor from Asgard and Thor begins a life as a superhero on Earth. Many years later Thor becomes romantically involved with Jane Foster. Thor brings Jane to Asgard to be wed and she is granted immortality but fails a final test.
In the post-credits scene, Thor and Jane reunited in London. The God of Thunder finally seemed committed to making their relationship work and balancing his responsibilities as a superhero and a boyfriend.
Sif does love Thor, but their attempts at relationship are always frustrated by the interruptions of another woman, be it Jane or Amora. After Jane's memories of Asgard and Thor were erased, Odin tried to arrange for Sif and Thor's marriage. It didn't work out.
Across multiple comic continuities, Thor has had several daughters including Brigid Thorsdottir, Thena Thorsdóttir and Torunn Thorsdóttir, the latter recurring in many iterations. In Norse Mythology, Thor had a daughter named Thrud with Sif.
Back on Earth, with amnesia forced onto her by Odin, she met her husband Dr. Keith Kincaid and had a son with him. Years passed and one day Jane became extremely ill on the verge of death.
The moment in which Love returns and takes the form of Eternity suggests that she shares many abilities with the cosmic entity. However, her being only a product of Eternity suggests that she might not have the full breadth of the entity's powers.
Torunn is the daughter of Thor and Jane Foster. She's a member of the Next Avengers. When she was a a child she's been looked after by her mother after Thor leaves on an important mission. After growing up she wants to know who and what is she and whats her father like.
Sif is a fertility goddess in Norse mythology, wife of the thunder god Thor, best known for the story in which the trickster god Loki cuts her hair as a prank and is forced to replace it with a magical headpiece, leading to the creation of several other well-known enchanted items including Thor's hammer.
Sif, unwilling to go along with this new vision, is exiled from Asgard. Thor eventually marries the Enchantress and has a son, Magni. As an adult seeking understanding of these events, Magni finds Sif, who influences him to rise up against his father even though she still loves him.
However, it would seem that what went wrong between Jane Foster and Thor is most likely tied to Thor's status as an Avenger and a god who only comes to Earth when duty compels him, which had been seen to cause tension between the pair leading up to Thor: The Dark World.
Robert Downey Jr is open to returning to the Marvel Cinematic Universe. In an interview with Esquire, the actor said he'd happily play Tony Stark aka Iron Man in future movies if Marvel gods want him to.

They reunite and finally get together at the end of Dark World, but Jane does not appear again until Thor: Love and Thunder; Thor: Ragnorak reveals they broke up off-screen. Aside from a flashback montage in Love and Thunder, the fandom never got to see Thor and Jane as a couple.
But when he reaches that cosmic being, he chooses to use his wish to resurrect his daughter right before he dies. Jane Foster promises Gorr with her own dying breath that Thor will take care of the child, and Thor, now heartbroken and alone, chooses to adopt the child.
Love being born out of Eternity means she is bound to be one of the strongest beings in the Marvel Cinematic Universe, with her small display just being a showcase. But her receiving these powers remains inexplicable. It can be explained as the Enigma Force might be what's responsible for the source of Love's powers.
