Did I sound like I was blowing him off?

Basically i've been with my boyfriend 6 months. We rushed things by going straight into a serious relationship and spending 24/7 together but now we're slowing things down. I always wanted all his time but now we have structure and planned to meet up tomorrow and sunday. We was texting just now, he was saying how he's got overtime at work but made sure wednesday was free for us to meet. I then thought I'll show how I'm letting him have his own time and being nice by saying 'we can leave wednesday if you want?, you can stay at work or go the gym or something? I don't want to get in the way' I really want to see him but now it sounds like I don't? He hasn't replied yet!
