Guy's Behavior

Did he lose interest? Shy? Afraid? Should I reach out?

A few months ago, I had a guy I briefly knew ask me if we could go on a date sometime. I let him know we could, but that I had just gotten out of a relationship. He was thankful I was up front and we talked here and there after that. He told me he had always been slighty interested in me even tho we knew eachother briefly. I was interested, but still very focussed on my ex, so when I kinda stopped hearing from this guy, I didn't think much of it. A few weeks ago, he reached out to me and asked if we could still go on that date sometime. I said yes and that I thought he had lost interest. He said he had not and apologized saying he is really bad with girls and reaching out. He was never super great at keeping the conversation going, so I never pushed it too much. He asked me to hangout the next day, but I was busy. He reached out a few times here and there. One day we talked for hours and it was super fun. He had quick responses, was very flirty and several times voiced his interest in me and I felt I really voiced back. I will admit, I got a little excited here as I really was feeling him and finally had just before that been over a toxic ex. I let him know that my next weekend was very free, if he wanted to do something, as he kept telling me to "take charge" in a way. His response puzzled me a bit, as he said "I am not sure what I have going on, so very potentially" I was kind of like.. oh. I breezed over it. We never talked daily, but after I felt we really connected, I wanted to. I reached out a few times during the week with light conversation or jokes and he responded. One night I was out with some friends and we spoke about being out Friday. I told him he should come out the next night to meet me and he asked where. I said a location and said I could meet him somewhere, too. The next day I reached out with a joke and he responded. Later that evening, I was out and I messaged asking if he was out. He did not open my message, but watched my story.

This was the first time this has happened and I will admit it got to me. I did not say anything, but I was pretty bummed. He did not open my message til the next day and he did not respond. I was a little taken back that he didn't explain or even make something up. A part of me took that as he somehow maybe lost interest. Or he got scared. He had voiced to me he was bad with girls and that he had not had a relationship or anything with a girl in 7 years and found himself blocking it off at times

even though he wanted it. I am still wanting to reach out to this guy, as now it has been 5 days. Which, before was not unusual at all, but, in my mind things felt more serious as we talked so much, but really we hadn't hung out so I don't know. Should I reach out? Was I ghosted?
