Dating as a single mom

At what point when you start dating again would you feel comfortable having this new person your dating over to your house? For some background I met this guy and we have really hit it off and stupidly invited him over when I was feeling a little something one night while my son was asleep and my ex found out and lost it. I agree it was stupid as I didn’t really know much about this guy and should have waited, I understand that. But now that we have gotten to know each other more and we have talked every single day since we first met we both feel waiting for my son to be gone is putting a bit of strain on us progressing our relationship further. I’m not comfortable with us meeting each others kids yet as I have seen it go so bad introducing children too soon. Also I don’t want to add anymore drama with my ex and his family as that is the only support system I have close by, by bringing my new guy over with my son sleeping( even just to hang out and spend time together). I just am lost on what to do and how to proceed and looking for advice.
