When I asked for my divorce, it was because we had both gone in different directions and the married thing was getting in the way of the friendship that started the whole relationship in the first palce. Since the divorce it has been up and down, but much easier to work through things as friends without the husband/wife dynamic getting in the way. (It also helps that she moved to Spokane).
Not always easy, but answering only to myself sure is nice.

Good luck Tim...
