Left a job around 6 months ago, stayed in touch with the group via a WhatsApp group, some more than others. There was a man I got on with, spoke to him around once a month on average on WhatsApp since I left, just about the job mainly and he told me about new developments in the company and so on, him ranting about the job and wanting to leave.
Whilst working at the company I knew he had a partner and young kids and he knew I was with someone. I thought once a month talking about work only was harmless.
I've just had a message saying 'You're gorgeous btw ;) xxx' I've told him that's inappropriate, I do not appreciate it and block.
Maybe blocking was an overreaction but he is not a close/long time friend. I am fed up with this, did I do something wrong? We only spoke about the job. It's just vile.
