My fiance has suddenly started pulling away from me

My fiance and I have been together for 6 years. I recently noticed him pulling away from me and it's been bothering me. I had not brought it up, because of his reaction in the past, anytime I have tried to tell him how I feel when something is wrong in our relationship, he gets very defensive and angry. Usually blames everything on me, doesn't actually hear what I'm upset about, and says very mean things. But while texting with him one day he noticed I suppose something was wrong and ask me seems like you have something on your mind talk to me. So I did. I told him that I felt like he was pulling away from me and I didn't understand why, asked if there was anything I could do to help him, tell him I knew he was under a lot of stress I'm just here to help. All those sort of things but yet he still got mad, turned it around on me, didn't hear what I was saying, denied pulling away, said I was making all of this up just to make him break up with me. He even told me to bent. I had expressed not wanting to tell him oh, but he pushed so I did. The next morning I woke up to a good morning gorgeous text. He said he was sorry that I felt the way I did but he did not know what to do about it. He also said that he did not want to talk in circles all day. I told him I had not planned on speaking to him that day but he didn't have to worry about that. I also told him I was too busy that day getting bent like he had told me to do the night before when we were fighting. 2 days later he came into town, he travels for his job I used to do that with him this past year but I decided recently to come home and stay home and get a job here so when he came into town I spent the night with him in a hotel room, we had sex, talked well he thought I was still hurt and still hurt and have nothing to say really or not a whole lot anyway. Ever since then and all of this has happened now he has stop texting me like he usually did, he stopped sending me good morning messages and goodnight messages. I messaged him this afternoon after not hearing from him most of the day and told him I missed your good morning messages that you usually send me. And his response was good morning my woman what are you doing today. But every time I respond he takes a while to answer. I just do not know what to do about this, I want to help him I love him we are supposed to get married in February. I just do not understand. Someone give me some opinions please
