Yup! Jane chose Michael, never looked back, married him and was happy with him. The only thing that parted them was a shoe-horned in death that the writers stupidly insisted on because they were too enamored with a plan they came up with in S1 to realize that it's okay for plans to change. I don't see how a bad coupling being "endgame" is anything to celebrate when one person is only with the other because the actual love of their life died. Like, congrats on being sloppy seconds, I guess?
