What are the signs of this Virgo man ?

Hello to all of you

I expect that you will give to me the best advise because someone of you have big or maybe the same experience as mine.
Here is my dilemma, why Virgo man contact me after the fighting because we didn't have a clear breaking, we saw each other once after the fighting, he have been distancing from me but still contact me and this three mounts he contact me more frequently, why he is still interesting about me and my life, he ask me some direct questions as What have new,questions about my life, why he do this to me, also when he would see me on the street he talk to me and before two days ago he saw me on the street, we say hello, what up after that conversation he spoke with me on net as where are you been when i saw you, and in the same night i saw him in front of the bar with one girl maybe he would go to accompany her, we saw to each other very incidentally and he was very surprised when he saw me and ask me who i am wait? he was also very cold with me as the world to come upside down.
Please explanations and advises what to do when he call me next time if he call, but i am sure that will....
