Hey Reddit, 
[throwaway account] 

First/Background: me [25]F, him [26]M. 
Length: about 2 months 
We met through a co-ed sports league, about 3-4 months ago. Flirting began, and about 2 months ago we first kissed. We kept it slow until about a month ago, where, we went from seeing each other 1-2 times a week, to about... 5-6 days a week. The past month he has stayed at my place about 3-4 times per week, and goes to work from there in the morning. 

We still play sports together, and we've been going to a lot of concerts together, or just hanging out. And things seem to be going amazing. We've spent a lot of time together, and he still seems interested. until today I feel a bit confused. 

I asked if he was planning on staying over tonight, and he said that it was "yet to be determined, i think i have a shirt in my car" to which i responded "You know, you are welcome to leave a shirt/ a few necessities at my place if you want, instead of lugging everything in and out, just an option." 

His response was not quite what I was expecting. "That's sweet. I feel more like a rockstar this way, always on the go... aka a sold out show in [area where i live]" I'm not sure if he was trying to be nice in shutting me down, was trying to be funny, or. what? 

Basically, for the men of reddit, [and/or ladies] - did I go a bit to fast in asking if he wanted to leave some items? I wasn't trying to insinuate anything crazy. 

We haven't had the discussion if either of us are dating/hooking up with anyone else, but with the time we spend together, it would be hard to assume he has the time. That, and we pretty much act like a couple around everyone. 

I feel like maybe I might be over thinking this as well....
<bot>: Told a guy that I've been dating if he wanted to leave a few items at my apartment, that he was welcome. His answer felt a bit like I got shot down.
