visited a girl for potential marriage and ended up doing everything but sexual intercourse that included hugging, kissing, oral sex Do these acts fall under fornication?

Salamalaikoom, I visited a girl for potential marriage and ended up doing everything but sexual intercourse that included hugging, kissing, laying naked on the bed, oral sex. I am a virgin and was not involved with a female before and am still religious. Hugging and kissing itself was too much for me and so one thing led to another but alhumdolillah Allah saved me from intercourse. Do these acts fall under fornication? What is the punishment for fornication in hereafter? The muslimah though was intimately involved initially saying that she liked me now says she does not want to pursue any further with me; saying that there are many differences between us but she still likes me, she has had a bad past and is a revert. We met 3 days in person and talked on the phone for more than a month now. I am feeling very guilty and repenting, I am interested in teaching her more about islam and pursue the relationship further to a potential marriage that we may repent and follow islam closely, Will that wash mine and her sins, what should I do? it is difficult for her to understand the gravity of the sin that has been committed. I feel all my good deeds are in vain.
