Getting along with in-laws better

Aaron • 23 years old. Married my best friend in October 2015! Not TTC until after I finish schools
Hey glow girls! I am getting married in October and I have gotten extremely close to my future in laws. However, it seems that as much as I get along with them, the less I get along with my actual family. I have always felt like the outcast in my family (I'm the youngest of 5 girls) and always figured that I was different. When I met my fiancé, I found someone that doesn't consider me to be different; and neither does his family. Has anyone else experienced this?
