Virgos are very interesting people especially from the point of view of a Sag. (me). Saggies are open and easy to read, but Virgo is deep and rather unemotional in their outward expressions.. My two best friends are Virgos (one a male and the other a female).
I agree with all the posts so far regarding Jenever's situation with a virgo man.
I think it is very selfish of your Virgo friend to expect you to wait around for 4 years. I would go on with my life and if it's meant for you two to be together, it will happen eventually.
Virgo is always looking for perfection which gurantees they will never be really happy because perfection is an ideal not a reality. They also tend to be very hard on themselves....very critical of themselves and others. Alot also depends on their ascendant or rising sign. I find that if they have a fire sign as a rising sign it helps to moderate these tendencies.alot.
Jenever sounds like a very level headed gal who has given all this alot of careful thought and seems very wise about her situation with her Virgo man. You could well be the love of his life.......time will tell. Good luck and many blessings to you.
