Subject: Please advise

Please help me. I am unable to decide anything.I am engaged and my marriage is after 3months.My fiancee is the only child for his parents.We got 8months time nearly between engagement and marriage.Now 3months are left out.I cant break this relation.I want some solution for this problem.Here is my problem I cant live without my freedom.specially in my personals things.I can adjust with common things but not with my personal things like my dresses,my accessories,my language etc.whenever i tell this to my fiancee he tells me that i am giving u complete freedom.But thing is he is not restricting ,his mother is restricting me.And my fiancee tell that i will give u complete freedom but i dont ask me about my parents.And he tell me that u shouldnt hurt my mother and if u hurt her i wont tolerate anyone.He tell me indirectly.His parents want me to talk in their way, like foe example, they tell me call him sir if i call someone with name or something else. I am feeling like i am loosing my life.If this continues for some more months i guess i may go into depression even.After all i have one life.Why they wanna live my life.they are trying to live my life.II cant live without my freedom. Please someone suggest me solution.I will wait for your response.Thanks and regards in advance.
