I'm looking for a story where Kagome's dad is from the past, but he was able to travel through time and meet and marry her mom. I think he's some kind of forest guardian or elemental, so he can never leave for too long.

Its a complete story.

Looks like no one knows this one either. I'm remembering more details:

Kagome's in the past where she meets an older man. He tells her who he really is later in the story. He also might be a god? Minor god?

She's upset she doesn't see him more often, and thinks he's avoiding her. They talk about that and he promises to visit more. When she's pregnant, Kagome's emotions or pain are making the weather or elements rough and her dad helps calm everything down. He might've asked why they didn't tell him she was so close to giving birth because he knew that would happen.

At the end, he's reunited with Kagome's mom and they live in a castle made out of wood. He can't leave for too long and if her mom agrees to be with him, that same rule will apply to her. I got the idea they could go on vacations, but can't be gone for months.
And I think Souta is her half brother and he went to live with Kagome.

Could be maybe Sunset Love by Aurora Nyte (rated MA).

Thanks! That was a great story, but not the one I'm looking for. Her mom wasn't able to time travel. Everyone reunited in the present time period.

I think your looking for "She Who The Prophecy Foretold" I don't remember who wrote it but it is MA, and not finished.

Thanks for the recommendation! I hadn't read that one, but that wasn't it. The story I read was complete and was HEA at the end.

It sounds like
Ultimate sacrifice
