I think you are continuing to do exactly what she said was the problem-- you are containing to ignore what she needs (space/distance) in order to make yourself feel better. She said she does not want to repair the relationship and instead of accepting that, you have called, emailed, and texted because YOU feel upset and insecure and you want to repair the relationship for your own reasons. You are ignoring the fact that she said she does not want to repair it and she needs distance from you so that she can take care of her own needs and feelings. What she is doing is not selfish-- people have the right to end friendships and take time to themselves when they need it. She told you exactly what she needed, and you ignored her to focus on your own needs again-- proving her point. If you want to fix your working relationship with her, then give her the space she has asked for and stop pressing her to explain more and try to repair the friendship. Part of life is people growing apart or realizing that they no longer benefit from certain relationships. It can hurt, but it's just something we have to accept sometimes. In order to take care of your own feelings (rather than rely on her to "fix" them by becoming friends again), focus on your other relationships-- your husband, friends, other family members, etc. Or focus on hobbies, work, or other skills/pursuits that make you feel good about yourself. If you focus on things that you do well or relationships that are satisfying, you will feel more confident and be less likely to let the needy/insecure part of yourself rule the show.
