My wife is 31 an she depends on her mother for advice in our marriage?

My wife and i have been married for 10 months, but we have been together for almost three years. Everytime we have a disagreament she runs to her mother who lives with us for advice, or as she may put it for venting. I have asked her to stop talking to her mother and that she will create problems in the near future.As a married couple she should come to me so that we can together FIND A WAY TO solve our problems, but our problems seem to get worst overtime. I ALSO TELL HER that asking her mother for advice will not make it easier for us and could potentially make our problems worst. She tells me that she will always run to her mother because she is her support system, and that no matter what i say she will always engage her. Her mother has made comments to me that SHE WILL NEVER ALLOW her daugther to become who she became when she married her father meaning that she should not go without doing her own stuff like going out and staying out late. The other day her friend came by and knowing we where having problems she asked her to go out only to bring her home at 7 am i told her that she could never again do that and that she is married , i also told her that her friend is not a very good influence on her and that her coming home so late is not acceptable .To me her mother is sending me a clear message that she is always giving her daughter advice on how she should treat me and is meddling. Lately she has this really lousy attitude and she curses and disrespects me whenever we get into a conversation, i believe that because her mother is there all the time in her ear, that she is being couched. I also believe that living with your inlaws are the most mind buggling, stressful situation any newly married couple could get themselves into, we have no privacy , need i continue . When we where dating i remember that whenever i wanted to take her out to dinner or a movie , she would invite her mother to come with us and the mother never said NO i always thought maybe one day she will give us a day where she (HER MOTHER) could stay home and take care of the kids for a little while so that we could have some alone time , but (YEAH RIGHT) ! But here we are three years later and everything is getting worst. And when we would go on vacation to Florida her mother would travel with us by car , and once there her father would join us at the resort. Only for the rest of the family to join us at the resort later on and this has been going on for the last three years . Last year for our honeymoon her uncle gave us a week at his resort, in Florida , and when we set out on the trip it was me, her , her two boys , her mother , her two nephews , and once there her father. During our stay there at the resort , and two days into the stay her two cousins dropped in and they stayed until we checked out of the resort to have no honeymoon . when we returned to the City in which we live , and moved into our new apartment we moved in only to have my mother inlaw move in with us, and i started to see a big change in my wife's demeanor. Now i have asked that she change her attitude and to stop disrespecting me in the presence of her mother but she thinks that she is right, and only continues to do everything i have asked her not to . PLEASE HELP ME MAKE UP MY MIND should i DIVORCE her or should i ask that her mother leave our home ? IAM tired of the fighting ? Is her friend a bad influence ?
