Should I ignore him?

Hi everyone, I’d love to get your advice on the following situation:

For a little while now, I’ve been dating someone I met through work (not a colleague). We’ve always had great chemistry and have been on fun dates with a clear mutual attraction. Dating still feels a bit nerve-wracking for me because I’ve been hurt in the past, but thanks to the amazing advice from this forum, I’ve learned a lot and I try not to make myself too available or come across as needy.

This past week, I suddenly noticed a shift in energy—something I’ve seen men do more often, according to what I’ve read here. He started contacting me less and even canceled a planned date because he was busy. Since he became a bit more distant, I’ve also taken a step back and given him space to do his thing.

We’re still in touch, and he does still ask questions, but we haven’t scheduled a new date yet. There’s a possibility for Friday, but he’s being kind of vague about it, and I have a feeling he won’t make any concrete plans.

If he keeps it vague, should I ignore him? I expect he’ll still reply to my most recent messages, but he might dodge the question about whether Friday works for him.

If he does that, should I just ignore him afterwards? Or is there a better way to handle it? I’m definitely not interested in vague or half-hearted communication—I actually want to see him, not just keep texting forever. I also don’t want to put more energy in this than I’m getting in return. Because things were going so well before, I’m unsure what the best approach is now.

What do you all think?
