Need advice.. TW.

When I was younger (15/16)

There was this man (I say man because he was 27) I met on the internet (facebook)

He was very nice to me and being young I wanted the attention, he would always drive me around and what not.

He was kind, and I trusted him

Months into it he started to be sexual towards me, at first not physical, but eventually it was.

He would always call me a tease, and make up uncomfortable.

I never told him to stop being that way, but always made it clear I didn't want to have sex.

He was always controlling, and mean about people I would see at school.

He would always drop into my work and harrass me.

He always told me not to tell anyone, or pretended I'm older..

He messaged me the other day and it made me very uncomfortable.

Did he do anything wrong, or was it my fault?
