We broke up after 3 years

My head is on pretty straight for this being my second break up and I’m 22y/o. I went to school and I tried to break up with her before I left and she said we could make it work. We in fact didn’t make it work lol. My mom said she was relieved we broke up and she wasn’t super super supportive, but she was always kind to her. I know healing doesn’t happen fast, but any tips that can help are welcome. I don’t want to see other people yet either. It ended surprisingly well, she will probably be moved on soon and that breaks my heart but I know how valuable I am and how much I tried.
