Am I getting cold feet?

I don't want to go into a lot of detail, but I am wondering if I am getting cold feet. I have been with my boyfriend for 8 months now. We get along great and have a lot of fun together. He has recently asked me to marry him and I said yes! A little background. He is a biker and he is a loner. He has been through alot of stuff including heartbreak. He was lied to and cheated on. I always knew that he was a loner, and that does not bother me. We are both strong willed people but I tend to be more giving. I am very happy with him. Well what is the problem you ask. I am wondering if these are warning signs of someone that is a control freak. He does not want me to walk in the morning before work. I used to do this daily every morning in the area that I work. He says that is because he worries about me and does not want anything to happen to me. 2. He does not want me to go anywhere without him. He says that he loves to be with me and wants to do everything together. 3. I am in a motorcycle club and he is not I was involved before I even met him. I want to stay involved but he wants no part of it. He does not want to be around my ex or some of the people that I used to be friends with. I am no longer friends with a few of them because they tried to cause problems for us, you know they tried to stir the pot. But I believe in what they do (all good causes) and miss being around some of them. Or am I just looking for trouble by wanting to stay involoved with them. I know there are 2 questions there. Please any input would be helpful..........I do just want to let you know that he treats me great....and said that he will make me happy. But he also asked me if I am sure that I want to marry him, I asked him why and he said that he does not want to lose me, and wants to spend the rest of his life with me. And he also stated that he will never change, and that others have left him because they thought that they could change him. I don't want to change him. I am curious as to his behavior....if it is along the lines of being controlling.....
