Tension

I have been married for 8 years . Though I hv loved her a lot but she does not understands me. She is only worried about her mother sister and brother. Even now and then she prefers her family and friends over me. She does not wish to understand from where and how I arrange money or how do i bring. She is always giving it to get mother. Her mother took a loan from me 2years back and had still not returned. I don't understand what i should do. Though still I love her. Whenever if I do some helpful thing for her family she becomes happy and awaits for my return ready to get laid.
