what did he mean

its really not that deep but I was just questioning my self and wanted to see what other people would think he was trying to ask.

this guy that I have been seeing on and off for the past three years (a no strings attached thing) right after we had sex we were getting dressed and I was talking about some new plants I got he just interrupted me and asked me if I have been going out (last time we saw each other was last year around april) It caufht me off guard because I was on a different subject. so I said what and he just started saying "well you know like going out like like do people even go out anymore, last time I went out was a long time ago, you?" I just said yeah like the movies and stuff I havent really yhat much. I thought he meant like kind of trying to catch up and stuff but one of my friends pointed out that he might have meant like with other people since he did seem a bit nervous when asking and just changed the topic real fast after that. Am I thinking too much into it?
