We've had two great dates and now I'm confused. Help!

I met someone last week. We had an AMAZING date. We met at a bar, then he wanted to keep extending the date, so we went back and forth between bars a few times. Eventually it became 2 am, and was apparent we didn’t want to say goodbye, so I invited him over. We spent the next hour making out and talking, and decided we’d spend the night together but we did not sleep together. It was a really lovely night. He left in the morning, texted me three hours later to say he had so much fun, and to have a great day. The following day, he texted me telling me he had finished a tv show we had been discussing on our date. I wrote back, and the convo ended there. He’s not a big texter, and is very introverted from what he’s told me, so I didn’t think much of it. On Monday, I wrote to him in the evening asking what he was up to, and how things were going. He wrote back enthusiastically, and almost immediately asked me out to dinner. On the day of our second date, he even wrote to me saying he was looking forward to seeing me in the evening.

We had our second date this past Friday (a few days ago). We met at a restaurant, had a nice dinner, which he extended into drinks, which extended into him inviting me to see his house. So we walked over, he put on music, we sat on the couch and talked. Made out for a long time. Pretty much similar to last week. Once it got to be around 1:30 am, we both seemed tired, so I asked how he was holding up, and he said he was feeling really tired and that he should probably go to bed, but would walk me to my car, and mentioned the idea of getting together this week to do an activity that I had mentioned earlier on in the date.

We made out some more, got off the couch, he walked me to my car, kissed me again, and that was that. On Saturday, he texted me saying, “Hey Kate, how’s it going? thanks for having dinner and drinks with me last night. Hope I wasn’t being too critical.” (the reason for that comment was simply because he was asking me a lot of questions on the date about my job, and I joked that he was putting me on the spot, and he apologized as he didn’t mean for it to come off that way). I wrote back, said i had a great time, don’t worry, it’s all fine, you weren’t being critical. How’s your day? He responded with what he did, and then asked me what I was up to. I responded back, asking a question about one of the things he said he had been doing that day. He hasn’t responded since. That was Saturday evening.

I know that was only on Saturday, and that my question to him wasn’t all that important, but in the beginning of dating, I would think the other person would be interested in me enough to at least get back to me. It feels like I was blown off, even with such a small thing like that. Isn’t it essential to remain connected more in the beginning, or are some men just.. not thinking that it’s a big deal?

I would just like to know, from reading all of this, what could this all mean? Should I just reach out myself? Is he showing me that he’s not interested? I’ve been learning that his pattern of texting is very basic. He’ll shoot me a text, I’ll respond, and maybe we’ll do a couple of back and forths with no real “goodbye”. He also usually only texts me to make plans. I also know that he’s had a lot of deadlines at his work, and had a lot of catch up work to do this weekend.. I just hope and pray that he wasn’t giving me an excuse. I always hear girls saying, “OH, he told me he’s going to be really busy” and that it’s usually a bad sign, but with him, I’m not so sure that’s true.

If he was no longer interested, would he have sent me that text on Saturday? Help!
