I would stay away from the emotional female side. Just let things go. Don't ask him when and why just except that it is and leave it alone. I'm also a Sag dating a Virgo male and he has already told me that he is in love with me and I didn't believe him at first and maybe still a little unsure but, he tells me what he loves about me and has only told me it once. To me, that says enough. I let him decide on why he feels that way and I don't push the issue. It's great to know that a Sag/Virgo relationship is working well.
