Need advice

Hi everyone. So i am two nationalities and live in the US. (I am half american) my mom is not american though and my dad is. Parents are divorced and I live with my mom. My mom and i have always been super close. I am almost 21 and have had to go through a lot after my dad left my mom and I will pretty much nothing a couple years back. Recently my mom and I have constantly been arguing. I feel almost alienated at times because i am developing a more logical mentality instead of being incredibly dramatic and emtional(as all the women are on my moms side of the family) my grandma and mom recently have really managed to get under my skin. They come after my boyfriend whos family has helped my mom and i financially because he has tattoos and “doesnt have goals”…. (He has a trust fund and obviously has a different approach to university and everything but he remains to be the most humble person i have ever met). He is very kind and we have been together for 3 years. Idk they just are so caught up with the idea of like going to the best name branded school in the US and living out that American dream life… my family isn’t the greatest with money and I want to change that cycle. I am trying to be logical but i am constantly reminded the “oh she has that American mentality” “she is not like us”. It is not typical to move out of the house in the country that my mom and grandma are from— yet i want to move out so badly. I live in a one bedroom apartment with my mom right now and have not had my own room in three years…. I have two jobs, have a 3.9 GPA. Yet they are so freaking opinionated… i tell them that some of the things upset me but they say that they can give their opinion whenever they want. This is an issues of cultures clashing and my logical part of brain becoming more prominent, especially with me growing up and maturing and seeing how a lot of these behaviors are toxic. I have been filled with anger i get so uncomfortable being at home and it upsets me because my mom and I have always been like sisters, but recently its like i cant say anything. No one listens to what i have to say and my family is pretty much my mom and grandma— who are super critical… i just dont know how to go about this. I live in the US and go to college here so i have to kind of emerse myself here you know. They tell me i live a boring life, but what much can i do living at home sleeping on the couch? Idk what to do..
