As-salamu alaykum - I reverted to Islam and I'm unsure about my relationship and next steps

As-salamu alaykum, brothers/sisters. I hope you're well. I want to share my situation and get some advice, please. I've been with a woman for almost two years. Before I decided to follow Islam I didn't practice any religion, and we were in a relationship. Recently I learned about and accepted the teachings of the Qur'an, and now I'm confused about what to do next. I discovered that having a girlfriend/boyfriend relationship like before is considered haram, and that worries me because I truly love her. My family actually likes her, and her family supports us as well. From what I've read, it seems possible to keep contact but under the supervision and knowledge of our parents, and to move toward a proper Islamic route like engagement and marriage. To give some background: we're currently long-distance because my family had to move for certain reasons, but we spent a lot of time together before. Back then we kissed and hugged, and I now feel ashamed because I understand that was wrong. We did not have intercourse. My main questions are: can we keep communicating while we try to arrange things properly? Is it allowed for us to text and express affection like saying “I love you,” or using pet names such as “love,” “baby,” or “dear,” given my new commitment to Islam? I want to do what's right and learn the best way to handle this so it fits Islamic guidelines. I would appreciate practical, sincere advice - for example about repentance (tawbah), talking with our families, proposing marriage, boundaries in communication, or other steps I should take. JazakAllahu khair for any help.
