Most Helpful Guy
It sounds to me like he is/was trying to use you as either A) a one night stand or B) As a rebound.
A lot of college/university males aren't looking for long term relationships. He most likely was just trying to make you think he is nice by being sincere.
I could be completely wrong, however I have never met this guy, so I can't make an accurate judgement.
If you'd like you could talk to him about it if you have his contact information.
Best of luck,
Have a great day :)
