Speaking from limited experience (two open relationships of about 2 months), I think there is a third possibility for the type of woman that would have one:
3. Committed and healthy hoping that this will lead to committed relationship.
Both of my open relationships worked well (although I moved each time and ended them). I know that at least one of them dated a time or two, but even at the time, I was sure she wasn't taking dick. it was more pro forma dating to show me that she was OK with the relationship.
I will admit that neither girl was, for me, a candidate for marriage. Being the needy, beta that I am trying to recover from, the only way I was able to push for this would be that I had other girls and didn't care so much if these women said "No, I'm out of here.". My $.02.
