I had two advisors for my master thesis. One, as my first advisor would take the theoretical part to guide me. I have been meeting with my first advisor once every two week and he has been examining each part of the text. During these meetings, he continued to tell me how good I am doing and I should keep writing in this way. There were never real feedback, which could be pointing out my mistakes.
So I developed a full confident in myself and in the work. He offered me that I should consider starting a PhD with him. In short, during the time I have been writing my masters thesis, he gave me all signs that he approves and likes my work.
My presentation took place a week ago, and was pretty much successful in my opinion and in the opinions of other people who came to listen. But at the end of the presentation, I received a totally different attitude from my first advisor. He started to criticize the work in a way he has never done in our meetings.
I was shocked about how my first advisor could not defend me and his own ideas in front of the committee and I am incredibly disappointed. Not only have I lost my belief in him and his judgments but also, I am now doubting my own skill of writing.
I am going to meet my first advisor next week and planning to talk about his twist of judgment and criticism. In this talk, I will question the PhD idea. I'm not sure though, how to put my anger, disappointment in right words, without making him feel that I am attacking to his personality. Also, when I asked him if we can meet earlier than next week, he refused. I have the feeling that he knows what i am going to say and now trying to construct a distance.
I know that trust is a very important issue in between the advisor and the advisee. If we will continue work together, I have to ask him an explanation but as I said, I'm afraid of my own frustration and if I cannot express myself in a right way.
My question is, would it be wise to express my disappointment in him, especially now that we will start to focus on my PhD? On the other hand, I need him to justify his inconsistency, which is quite crucial for me to keep working with him.
