Very new, seeking clarity

Hello all, totally new here :) I will be somewhat limited with any distinguishable details as I do not know who may ever read these and I am a little desperate for some advice/opinions. I am a naturally dominant woman in many ways, but also very feminine. I am not a professional dom and have otherwise only engaged in vanilla relationships until recently. I matched with a dream guy online and it came out rather quickly that he has some submissive tendencies. At first I was put off and questioned his sexuality overall, but was willing to listen and we had a healthy discussion. We continued chatting and getting to know each other on pretty much a surface level and then decided to talk on video call. We were on the phone for 2-3 hours and had such a good time that he decided to come see me the next day. I must add that my primary attention was still focused on someone else throughout this initial encounter so i was somewhat reserved and cold. I did not show him must interest. I was also getting confused being inexperience not knowing if as a submissive that would be something he wanted. So he came to see me and I was absolutely blown away and so so flattered, but I of course didn't express that. I was unbelievably nervous, but we were not very awkward around each other or anything. He actually stayed and hung out from 3 in the afternoon to 11pm. Intimately we seemed very compatible and I know that he truly enjoyed, so I do not find that to be the issue. I believe it was more due to my cold and fake personality that I displayed because it was something unfamiliar for me. I did not offer to talk to him on the phone on his drive home, I figured maybe he wouldn't have wanted that, but maybe he did. I did the bare minimum of anything. I made him feel unimportant, replaceable, and unnoticed and I really regret it. We spoke minimally after that day and now pretty much not at all. He did intially mention wanting to go out somewhere we talked about liking together and when i asked him when he simply said "just some weekend on short notice your schedule is flexible." i then told him that i would be deleting snapchat and he instantly texted to make sure that i had his number. so although he is mostly not speaking to me, he seems to want to have access to me. I am leaving a lot out, but based on what is here, I hope I could get some suggestions on how to move forward or what anyone with experience thinks could be at play here. Thanks
