Is it me, really, is it all my fault?

Relations with both my parents and my inlaws have gone very very sour. My relationship with my husband is very stressed and slowly getting worse. We have a lot of financial issues, relational issues and personal baggage we both deal with together. I have been changing over the last year, I don't know how it happened exactly but I no longer take crap from anyone. I stand up for myself, I am tired of being pushed around and treated badly. So I started being honest with people about what I think and feel and I ert my likes and dislikes but now I feel like my world is crumbling down and my question is, is it me? Am I doing something wrong?
