Im glad youve made an honest change for yourself. Youre a good person and we make mistakes sometimes. Sometimes our mistakes have collateral consequences and its our responsibility to clean that up. If none this working for her, then consider actual therapy. She seems like she has insecurity issues that couldve been cause by you and maybe a lifetime of selfdoubt.

When i went therapy, my lady told me the best way to heal yourself is Self Awareness, Self Love and Self Acceptance. She needs to be sure of herself and honestly, thats not something you can change in her, just support her on. She needs to practice being comfortable and accepting herself first, and then you can just support her with that decision. You guys cant move forward until she recognizes her own selfworth
