Most times when this happens each partner has their own set of expectations. Being friends is certainly not being in a relationship. If this can't be worked out then you should consider how to end this civilly. You shouldn't be pressured to be friends. If he wanted a relationship then he would not feel pressured for any reason. Even if he does there is always a compromise. It doesn't have to be one or the other. Why can't you work together to make a better decision. I would talk to him to see if this is his final decision and what other solutions would work just as well. The key is communication.
