Interfere in a married woman’s relationship in islam

Assalamu Alaikum I was in an on and off relationship with a girl for last 15 years where my intention was purely to marry that girl. However due to some reasons the girl was always reluctant about marrying me and she never gave me the chance to ask her hand in marriage. Last year she got engaged and nikahfied to a person post that I completely disconnected with her but my heart was always heavy because I loved her unconditionally to the limit where she became irreplaceable. Now after her nikah she connected me again and asked to help her get rid of her wedding as the rukhsati is yet to be done. I prayed alot for our union. Now I am at a point where I am unable to find any way to go. I am in dire need of help. We are again in touch and she is continuously asking me to help her end her marriage as she is not willing fully in that wedding and also she cannot confront to her family as well.
