My mother

My mother hates my boyfriend. HATES. She thinks he's taking her time away from me. It's like she's jealous! I'm 20 years old and I want to pursue my boyfriend because I love him. She has torn up my relationship with her and is getting too involved in my relationship with my boyfriend. I don't know what to do, she needs to realize that I am gonna have a significant other in life and im not always gonna be there with her 24/7. My mom needs to let go and I don't know what to do.
