I would seriously question his motives for doing what he is doing. I don't believe in combining friendship and therapy. Being personally involved with someone should automatically disqualify that person from pursuing the role of a healer in the relationship whether he charges for his "services" or not. In friendship it's ok to fulfill our emotional needs and this fulfillment is mutual. In therapy, or any other healing service, a practitioner shouldn't try to fulfill their emotional needs in relationships with clients. Clients could get something from a therapist on the emotional level but not the other way around. There is no mutual fulfillment of needs in therapy like there is in friendship. Therefore, the role of a therapist and the role of a friend are mutually exclusive IMO.

So, if your "friend/therapist" is so "selfless" and appears to be only a giving party in relationships with others what is he really getting out of it? I do believe in altruism, but altruism also gives deep satisfaction because it satisfies our higher spiritual needs, not emotional/relational needs. From what I've seen, people with purely altruistic intentions don't pursue personal relationships with those they are helping and don't attempt to fulfill their emotional needs in those relationships. Their higher spiritual needs such as feeling that their life has a purpose and that they are contributing into making this world a better place are more important to them than to find somebody who'd satisfy their emotional cravings. When those people help others they don't become friends with them not because some ethical code tells them not to do that but because they don't have the need to do that.

When someone puts himself in the healer's role in a personal relationship it creates a power imbalance and a potential for abuse especially because that person doesn't have to abide by any code of ethics. And if he attempts go get closer to you and more intimate, that makes you even more vulnerable so I completely understand why you don't trust him. Someone like him would freak me out to be honest. It looks like you know pretty well that he is not to be trusted. So what's stopping you from distancing yourself from him? This is clearly someone who doesn't have any insight into his own motives and behavior and is incapable of acting in his own and other people's best interests. But that's not the most important thing. The most important thing is for you to understand what it is in you that doesn't want to stop the existing dynamic.
