Did I Make Him Anxious?

There’s a guy I’ve been talking to for a few weeks now, and we get along really well. We’ve went out about 3 times already. We haven’t done anything physical or intimate yet (except hugging), and we both are looking for something serious.

On the last date, we went to the movies. After the movie I was trying to spend more time with him, but he abruptly said he had to leave, we hugged and then went our separate ways. He then texted me later apologizing for leaving early and said he was feeling anxious. I told him I understood, and that hopefully we could go out again soon.

For some reason though, I can’t stop thinking about it. I feel like I was the cause of his anxiety, and that he may be starting to lose interest in me. I REALLY like him, and want to pursue a serious relationship with him, but I’m worried that things may be different now. We haven’t texted much since then (both our work schedules are weird so we haven’t texted much the past couple weeks, to be honest) and currently don’t have any recent plans made to go out again.

Do you think I made him anxious, or is my own anxieties getting to me?
