Suggestions as to why she may be like this:

-She always wants to write a well thought out response to you, but seldom feels like she has enough time. She may feel that it is better to keep you waiting than you send you a half-assed reply. She wants to be able to devote her full attention and consideration to you.

-Similarly, she may be overly perfectionistic in other areas of her life. She passionately wants to pursue all sorts of things, but doesn't know how to manage her time.

-She's a procrastinator.....

-She has unrealistic ideas about love or fears of love. The fact that she is continuing to pay for eharmony shows that she does want to use the service, but perhaps she doesn't know how to manage it properly. Perhaps she leaves the matching on all the time, never wanting to miss her soul mate, and then gets so many matches that it becomes a daunting task to sort through them and communicate with all of them. Or perhaps it scares her to find herself connecting with you, so she avoids it, even though she wants to find a relationship.

-You mentioned that she is the only woman to respond to you so far. It may be that she hasn't had a similar experience. She may have more men wanting to communicate with her than she knows what to do with. The fact that she has written thoughtful messages to you suggests that she is sincerely interested in you, but she still may be overwhelmed by male attention.

-Or she may just have a really busy schedule. Sometimes the simple explanation is the right one!

I disagree with the assertion that she just isn't interested. If she wasn't interested she wouldn't write or respond at all. I think you should tell her the truth- that you've enjoyed getting to know her and think she has many of the qualities you're looking for- but that you'd also like to take the "relationship" further than e-mails every week or two. Find out if she'd like to talk another way- over IM, the phone, or in person- something that doesn't take time in the same way that writing a long e-mail does and provides a more immediate response. All of the qualities that have drawn you to her exist despite her fault of being a slow replier, so I think she deserves a chance. It may be that she has too many barriers to be a real dating possibility, but it is definitely worth a try. She may have good reasons for being the way she is. Everyone is different. Good luck! :-)
