Would they be Thoster or Thane? It won't matter now anyways. According to EW, there has been a breakup in the world of Marvel movies. Thor & Jane Foster have called it quits. Marvel head Kevin Feige quotes: "We wanted Thor to encounter somebody that was near his equal & that his relationship with Jane may have evolved in unexpected ways in-between "The Dark Word" & Ragnarok and we wanted to pit him against a character who was much more his equal & in many ways his superior." He goes on to mention Valkyrie wanting nothing to do with her heritage, Thor thinking it will bond them, & her on the complete opposite side just wanting to forget it altogether. As superhero stories go though, at least they didn't kill her off.
