I am currently trying to figure out if this situation is "in my head" or if I'm sensing something from which I should just walk away.

I don't date a lot and I haven't in awhile. A lot of that is from getting in a long-term relationship a few years ago and just not being ready, and also because I hadn't met anyone I was really interested in. I feel reasonably well about my looks and my "normal" personality (the one I have when I'm not letting anxiety and depression take over) and I get positive attention from men.

About a month ago, I went to a small get-together organized by some old acquaintances, which was really a huge step for me because I almost didn't go. While there, I had a pretty good time and a few guys seemed to be into me. One in particular seemed very interested. We'd already been connected on social media but started PM each other more regularly.

Finally, we agreed to go out. I was looking forward to it and I got the impression that he was, too. Date one was great and I found that I liked him a lot. He was definitely giving off the same vibe. More conversations and texts led to a second date. It was longer in duration and equally fun. We talked the following week about potential locations for dates and he even suggested doing something together that was happening in December.

The problem? I suggested meeting for a quick breakfast or lunch. It's possible that it got overlooked because we were chatting about so many other things. He mentioned that he thought we had a great connection and wanted to introduce me to some friends. A few days ago, I asked him what he was doing that day and again suggested lunch. He was busy that day -- which, not a problem -- but said he was looking forward to "getting together soon." He kind of ended the session with that and I said cool, we'll work out the details soon. However, he hasn't reached out to me since then. I haven't contacted him, either.

So, I'm feeling a change in the energy, just from the way he seemed to abruptly end the conversation. Since we began communicating more regularly, we haven't really gone more than a day without at least a "hi" or some sort of conversation, like "How's your Monday going?" I don't know if I'm wigging out unnecessarily, because I tend to worry about things I don't need to, or if this is his passive way of backing off.

Up until now, I really got the impression that he wanted to spend time with me. He's been very up-front about that and has even mentioned it to our mutual friends. I feel like it's important to add that we've had some very lengthy, in-depth conversations and we're obviously attracted to one another (it hasn't progressed past kissing). But this is more that I "feel" like something is off, even though it's just that he hasn't spoken or texted in a few days.

So what do you think? Should I just let this die a natural death or is there reason to believe that he is as into me as he's said?
