I don't know anything about a relationship let alone marriage

Hi guys. This isn't really an update. Looking for advice. If anyone has seen my posts me and my husband are in an arranged marriage and have been married for a month. We have our first date tonight. I'm 18 and he's 23. We met for the first time at our engagement party when I was 16 and he was 21. And then never saw each other again until a few days before our wedding. He didn't really talk to me when we first met. He looked at me and was stand offish. He was like that for a month if our marriage too and just recently I broke the ice by asking him about his books because he had texted me asking if it was still ok for him to continue his book of the month subscription that was 15.99. He had it before we were married and wanted to make sure it was ok for him to still have it. We talked about his favorite books and he recently started giving me rides to school. He's quiet and awkward but seems to be getting a little bit more comfortable around me. Today he even helped with my Algebra 2 homework. I'm graduating this school year so I'm trying hard to pass. I'm excited for our date but I just realized I have never really been in a relationship. My parents forbid it and wanted me to stay "pure" for my husband. I'm not a virgin but the guy wasn't someone I dated. It was a weird pure pressure thing. I do want to try to make things work with my husband but I know nothing about being in a relationships and I'm married. IDK all the red flags I'm supposed to look out for. What if I am a shitty partner because I've never been in a relationship. IDK is my parents marriage was good because I have nothing to compare it to. How do I know if he's being a good husband? How do I know if I'm being a good wife? What red flags are there and what are things that I'm not supposed to do. I don't think we are anywhere close to having sex. But when that comes... It just hit me that I actually don't know what I'm doing and I'm getting anxiety. We are going out in an hour and all that's running through my head is "What if I end up getting abused?" "What if I'm abusive?" Maybe I'm being dumb but I would just like some advice my parents never gave me.
