Relationship therapy going bad

Hi, I have had 2 sessions of relationship therapy with my boyfriend. He has started to emotionally withdraw from me and it hurts like hell. Is this common at the start of couples counceling?

More information: I have been going out with my boyfriend of over a year, we do not live together. I work with my ex and my boyfriend can't deal with it. I can't get an equivalent job so I have to continue to work with the ex. For the first year of our relationship my boyfriend has made me feel very bad about this, he has behaved in a controlling way towards me. He doesn't like me spending time with friends who also know my ex (all of my friends). He makes me feel bad about going to work, seeing my friends and also not including him in my life. I tried to include him but he behaved badly which embarrassed me. I still try to include him but he always finds some reason why he can't come along yet still complains that he is not included. He refuses to acknowledge that he has behaved in a controlling way towards me. He has a lot of serious problems which I have supported him through. It is due to the amount of support I have given him that after a year of being treated with suspicion and generally made to feel bad about living my life I have pretty much had enough. As a last dash attempt to resolve things we went into couples concealing. In the first session he said he felt jealous. I felt so relieved by this as its the first time he hasn't simply blamed me for everything. In the second session he denied being jealous. The therapist asked me to go into detail about his his controlling behaviour which I did. I found this very upsetting and because this is an issue of emotional abuse the therapist said I could have a session with her on my own if I wanted to. I don't want to however my boyfriend has really latched onto this and told me last night that I had to go by myself today to see the therapist because the therapist was really pushing for me to do this. I am now concerned that he is going to use the therapy as yet another way of undermining, controlling and abusing me. He has also started to emotionally withdraw from me. I asked him if he still wants to be with me, he said he does, so I guess the emotional withdrawal is just a way of punishing me. This is hell and really frightening. I went to the therapist for help and it seems to be making things worse. I feel like she has handed him a free licence to completely deny he has done anything wrong.
