I need advice about boyfriend and his family?!! Help?

I feel that my boyfriends family is really overbearing. My boyfriend is 32 years old. I feel like they overstep boundries and are very inappropriate. They, mostly his mother have to be involved in every aspect of his life. He lives 5 minutes from his parents and 2 minutes from his sister. He goes over to his parents house atleast 3 times if not more a week. He goes shopping will his mom, all birthdays, holidays, events have to be spent with them. They have to know everything! This has always bothered me, and caused a huge rift in our relationship. I feel that there is no us. He will turn to his mother for everything. I want to have a life with him, get married, have children. Him and I venturing out to start our life. But he doesn't see it that way, he just wants me to jump into his life and be one of them. By no means am I trying to take him away from his family, but is unreasonably to ask for us to create our own life together, maybe cut visits down to once a week. Today was the end of the rope for me. He got in a car accident and went to the ER, he was fine, he just went to get checked out. Of course his mom goes to the ER and when he gets discharged says goodbye to me, and goes with his mom. Shouldn't I be the one to go get his percription, take him home, make him comfortable. Isnt that my job? Then later then day I went over to check on him, and we were laying in his bed and his Mom, Grandma, sister, and two nieces come busting into not only his house, but bedroom!! Is this normal?!? I eventually felt so uncomfortable sitting on his bed with all of them I got up and left. I'm so devestated because I'm so in love with him, this is just way to much to handle. My boyfriend thinks they are a little annoying but otherwise thinks this is completely normal. Instead he thinks I should just be MORE involved.
