Please help me not break no contact

Have been in no contact with my ex (26F) since the day I (25M) walked out her apartment 6 weeks ago when she broke up with me. Have not spoken to her since then and she has not spoken to me. I’ve been mostly going through the motions of the breakup but today for whatever reason has been really bad for me when it comes to wanting to reach out. It’s taking a lot for me not to reach out.
