Search Results: different after sex

I had this immediate connection with a guy I met for the first and last time one evening (no sex). My best friend of 10 years who doesn't believe in those stuff keeps calling him my soulmate saying she never saw me click so much with a guy before.
I never got in contact with him after that evening as he lives in a different continent and I'm scared of creating anything long distance but I know his co-worker/bestfriend. I can feel him when he is getting bored, being scared, feeling pressured and just know that these feelings are not mine but his. I never ask but I always got confirmation by his friend that indeed the random moods I felt were his...
I feel like I'm going crazy I never felt so attached to what is truly a stranger but with whom I feel like one so strongly...
Should I start thinking these are all coincidences and that I'm going a little crazy or should I follow the feeling and maybe got meet him again to figure it out?

The typical player pumps and dumps and that's it. He's either gone after sex or mininizes his visits afterwards.

However, a user is different than just a player. They can go all the way to forging a complete relationship, get sex, companionship, romance, tell her fake promises of marriage and even get her money. They can even lie about their real age to both get her trust and get in her pants. I've read a couple horror stories from girls that were used in all ways, even had their money stolen too. Those users continued the act for years until eventually getting caught. By then, the person that got used has been greatly affected. Then he would finally be gone, after causing much damage.

No normal person would go to that extend. Honestly are users like that also sociopaths?
