I dont see what you have to lose if you are committed to continuing your therapy anyway and getting through even if he does reject you. But Im not sure you should involve the therapist unless she is honestly seeing progress and happy to put in a good word for you, it might be a very uncomfortable situation for her to be put in given their work relationship. I suppose there is no harm in asking but be aware that its not a betrayal if she disagrees. Im so pleased to hear you are going so well though, keep up the good work
