What is considered controlling, does this fall in that category?

My bff and I have been very close for about 13 years. I have been there for all her children when they were born and she has always been there for mine. She has no siblings so I am it. We are not intimate or have nothing to do with each other like that and we have just always had each others back. We are like sisters. She has been married for about 15 yrs. Her husband accepts me like we are blood sisters. He respects me and I respect him. When it comes to her husband she lets nothing come in between them and I admire her for that. She is very much in love with him and they are great together. They can talk to each other about anything(seriously). Well I have been with my fiance' for about 2 yrs and he knew how close we were when he and I met. I used to talk to her like everyday just about girl stuff, the kids, current events and things like that. He works everyday from 8-5 and most of the time (about 6 hours) he and I are on the phone. So I have no time to really talk to anyone else on the phone because I talk to him so much. After he gets off work I make sure that I don't have anything planned so he and I can be together. It seems like he is unhappy with everything that I do because he is always right. He is 10 years older than I am and he lets me know that often. I really love this man very much because he is really there for me but he is trying to keep me in a fish bowl. I have been planning to leave him without telling him. Just the other day I asked her about coming to her apt complex and she and I hit the gym 2-3 times a week and he got pissed. He told me that it would be too much time with her. He says that "women shouldn't be running after each other like that". I was upset with him because he thinks that I'm a h** because he has this idea that she and I are intimate. This really kills me! I have not been hanging with her(she's the only friend that I can trust, hell she's my only friend) at all because of him. We used to have lunch every other week but he thought it was a bad thing so we haven't done it in quite a few months. When my daughter got sick about a month ago, she immediately showed up to give support. We have always been there for each other family and all. I don't understand why my fiance' doesn't care for her when he doesn't even know her. They have never really been around each other except for one day when she was dropping my daughter off from a weekend with them. She wasn't planning on getting out of her van but the kids were having a fit to give me a hug and a kiss. Well she got out of the van and he found out that she was there so he left work in a hurry and came home and looking at everybody all mean. He said that he was upset because she didn't have on a bra. Well hell I never noticed that she did or not. He should have no reason to dislike her. She is always trying to walk on eggshells and respect the way he feels because she cares for me too but he doesn't give a rat's butt about how she feels. I am so torn between them because I want both of them in my life but he is not giving in and I don't think he ever will. He doesn't want me to do anything that doesn't involve him. When he's at work and I say I'm going to wal-mart, he says for me to wait for him. Everyone he comes in contact with is his COUSIN so therefore when it's more to him than friends. I have always been there for him and have not given him any reason to distrust me. We are together all the time. But when he wants to go to an event that his "FAMILY/COUSINS" are at I always agree and go with because I love him. My only family here is my best friend and her family and when I ask him to do something with them as simple as dinner he doesn't want to. I am seriously planning to leave him and it's not because he doesn't like my bff but because I think that he is going to get worse if I marry him. Is this controlling or am I just overreacting?
