I dont know!!

So I have this new boyfriend that I have known for about 3 years now and we just started dating for about a week and half now. I meet his family and they like me and he has meet my family (my mom and 2 younger brothers) and my brother like him but my mom doesn't. When I try to talk to her about him, she always bashes me about how I go guy to guy and I should worry about myself and my future. When I try and talk about my future, she doesn't care and says I should have a guy in my life. I'm 20 years old and have a full time job. I know what I'm doing about my future. Why does every time me and my mom talk about something except for work and our day, I feel like shit and what I am doing is wrong?? I don't know how to feel and how to think.
