Virgo woman doesn't want a relationship?

by Saggitarian Man

I've fallen for a 30 year old Virgo woman, whom I love and adore. We met 2 years ago while we were both living in a foreign country. We both moved back to our own countries (on almost exact opposite sides of the world!) about a year ago. We get along great, and often talk on the phone. She had invited me to visit her in her country numerous times since we parted. I will be spending Christmas with her this year (my 4th trip to see her this year).

I have told her that Im crazy about her and want a relationship. She has told me she isn't interested in a romantic relationship with me. That was on my first trip to visit her. If she isn't interested, why would she keep asking me to go back there? Am I being 'screened' to see if we're suitable? It just doesn't make sense to me. I keep going back to see her because I feel that if we spend enough time together, we may have a chance of starting a romantic relationship.

My question is, am I wasting my time? Do Virgo ladies usually spend this much time with someone they know is interested in them, if they don't think they will ever feel the same?

Thanking you all in advanced!
