Should I cut my long hair??

Ive been growing my hair for 3-4 years and haven't touched it. It's become a huge part of me and I'm not sure I'm ready to get rid of it. It's so beautiful and long, I feel like losing it could really take a chunk of my heart with it. The only reason I'm thinking to cut it is because of split ends and lots of hair breakage from having to yank on my hairbrush to get tangles out.
