@nyetek I am sure he did blocked her. Most people ghost and block. Unfortunately how you treat others and would like to be treated has totally been lost in the mists of time.
I actually do not think you need to give a lengthy explanation as to why you don’t want to see someone. A ‘I really don’t think this is for me’ is fine, and blocking is totally acceptable. Who wants to go through all the abuse when someone’s ego is bruised. I can assure you if they have said they are not interested, they have deleted and/or blocked your number.
