While life coaches may not have the same code of ethics we therapists do, I’m pretty sure they don’t have relationships with clients. They are also generally not trained or skilled enough to deal with and help you work through transference and counter-transference. You seem to be experiencing transference. If he is experiencing counter-transference and doesn’t realize it, this could get messy. When I’ve been faced with this situation, I explain transference, and then refer them out to a different therapist.
