Hexagram 28: 4,6 to 57 for relationship and Hexagram 13: 2,6 to 43 lessons learned

Hello!I am new to hexagrams and this community, so hopefully someone will help me to understand what is the interpretation for my questions, which I hope I asked properly. Basically questions are about a guy I met. I am an introvert so I don’t socialize with people quickly. But I met this guy, he gave his number to me. I somehow contacted him a few weeks later. He invite met to dinner. Then we met over a coffee. He invited me to his house next day. But I didn’t want to become intimate and changed plans. He is really handsome and I am very attracted to him but inside he is totally different than me and the values I stand for all my life. And I have this feeling that does not leave me alone not even a second that he is not trustworthy. And yet again, we met a few weeks later and became intimate. I am quite confused now. Despite all the differences we have, we are having a good time when we are together. But I can’t get over this feeling that there is something untrustworthy with him. I know that he is a womanizer, I know that he has problems with his finances and his work. So I keep saying myself that this is just a fling however when we are together, especially after we became intimate, I felt like he was expecting something more. I told him in a very kind way that I am happy with what is going on but I am not expecting us to become a thing. He seemed he didn’t have a problem with that but he still continued to make plans for having a romantic weekend getaway, introducing me to his best friend, going to his hometown etc. He invited me to go out for a movie night this weekend. He was going to work for long hours on Saturday, that’s why instead of saying yes, I told him to call me if he still feels like it after working all day long. He didn’t call. I didn’t call either. Now I feel like, if I don’t call him again, he will not call me. So it is a good thing, I suppose but considering how we met and how our lives crossed each other without knowing each other - because we understood that we studied in the same school for three years and didnt meet once, his work place is next to my best friend’s apartment, where I spent at least two days a week- I can’t stop thinking about what is this out of the blue thing about. This is why I asked two questions; 1- What should I expect from a relationship with him? What a relationship with him would bring my life? Hexagram 28: 4,6 to 57.From which I understood that my gut feeling is right, as “prepondence of the great” reflects a serious threat’s approach. With the changing lines mentioning an emergency management, I do not have any idea what are they about. Hex 57 says who understands the causes, understands the effects and know how to act. 2- What lesson should I learn out of this situation? Hexagram 13: 2,6 to 43. Hexagram 60: 1,3, 6 to 57. What I understand from both castings is that I have to learn my limits as well as I have to learn to make a decision and follow it. I know this was long but I would appreciate your comments. Thanks,
