New Potential Fling? HELP

Hey guys I want some advice and/or opinions. So I met this guy and we talked for a week. I made it known from the jump I did not want to have sex and I wanted to wait for marriage. I told him I wanted something serious. He doesn’t live that lifestyle but told me he wanted to see where things would go regardless of those terms. We hung out at his place for the first time. I know I probably shouldn’t have done that but I did. We watched a couple movies and he wasn’t pushy at all. During the second movie, he knew I was kinda nervous but he reassured me and kissed me. We were just cuddling and feeling eachother and kissing. It was nice. The thing where I don’t know if I messed up on or not was I have him oral. I wanted to he didn’t ask. I just did it and everything was fine. He invited me to stay over since it was late and in the morning we just spent the morning together be affectionate and laying down. Obviously we didn’t have sex but I actually am interested in him now. When I left, he gave me one of his hoodies to go home in and that was that. I went home and he texted me and eventually the texts ended up him leaving me on read last night. It wasn’t a big deal cuz we weren’t talking about anything serious but still? I am trying to play this right because I know he has to make the move now. The ball is in his court basically. I started overthinking this morning and just feeling bad because idk if me doing oral made the cause worse or not? My friend tells me I haven’t ruined it but I have to be tactical in how I play this. I definitely want him to be interested in me. What do you guys think?
