I got to know this girl from gym- she works there.

One day- she called me up and said she was fired from her job. I got to know that she was having affair with the gym owner who is married.

Me being a gentlemen took her out for coffee to listen to hear her stories.

From that day on- she called me everyday- talking about everything. This go on for like 2 weeks- she would talk for hours.

I tried to help her get a job- constantly updating her any openings.

She got a job- then notice her behaviour change.

One day- she ghosted me and blocked me on whatsapp. No reason given.

I felt quite bad- sumting like im being used.

I wonder what wrong i did
  P.S :  During our phone conversations- i did mention to her that i like her as a FRIEND only.
