When He's Being Unreasonable

From the last few posts I've made, it's pretty obvious that I now have a semblance of a normal love-life right now. We're not together or anything. We really are just dating and trying to figure out if this will work out for us or not. This Friday though, I got really pissed off at him because he asked me the stupidest question ever.

We've been going out on an almost daily basis. Then suddenly, last night he asked me via text, "Are you dating someone else?".

I got really mad after he asked that question. I have no idea where that thought came from or even what drove him to ask that. I barely have time outside of work. I exert a lot of effort to squeeze him into my schedule and this is what I get?

At 1 AM, he texts me, "Are we okay already or are you still mad at me?"

All I could reply was, "Just go to sleep. I'll talk to you tomorrow."
