Is it a friendship?

it's plainly business without engaging public relationship my dear... he just want to sell his products and when he feels that you really are very much interested of bringing your friendship again, he make it a way in order for you to trust him.

I'd say that he probably isn't your friend. I would not call it a friendship until you are able to talk easily and regularly, and that is certainly not the case here. I feel sorry for what he did to you, and he should've have ever done that. If you really care about being friends with him, try to keep calling him. Personally, I'd just drop him. Someone like that is not worth the effort to try to stay friends.

I dont think that it was a friendship attempt from your friends side and just a selfish attempt for his profit. you did your responsibilities very nicely and held a friendship hand to him again after so many years but may be your friend was not interested in your friendship rather than in his work.

I would not call that a friendship at all. He used you just to make a sale. It is awful what some people will do ot others, especially these days. I definitely would not consider them to be a friend.

Well he is possibly scamming you which is very sad and quite rude. It might not be the case that he was trying to scam you though. I did for a while in my life try my hand at being a salesman. I am definitely not a people person, and after I worked the job for a little while I found out it was not for me. If you start a new sales job they usually tell you to start by talking to your friends and family and try to deal with them. You are supposed to get "leads" from them and then you keep expanding a list of people to sell to. He could have tried to do a job like this and it didn't work out. I know I felt sort of bad for a while for putting people through the process. Some bought stuff from me others did not, but the quality of the product at least was very good.
