Am I making a big deal?

I have been chatting with a guy for about two weeks and long story short today I asked him when is the last time he has been on a date and he said just last night I met with someone for a coffee date. I was not expecting for him to say that and anywho it really triggered me because I thought it was kind rude even though I asked he was honest. I dunno I guess I would have just not said anything about it.
