Hey Jenn,

When I fell in love with my partner of six years we were best friends who fell in love. We were friends for close to a year before we crossed that line because we wanted to see what the other was really like.
What I hear you saying in your post is that you are okay with having this person as a friend but that she does NOT have the qualities you seek in a partner. That to me answers your question of where to take it. It sounds like you are the stable one, you are HER anchor. But what about Jennifer? I think DavidStrong nailed it with what he said. You can't put your needs aside to be there for someone else. It may "work" for a time but not, in my experience, in the long run. I would say be her friend as you feel comfortably able to, but do NOT compromise your standards. Don't settle. It's not healthy for you or for the other person, and you might miss out on a great woman with the very qualities you are seeking, simply because you settled.
Namaste,
