Is he afraid or is he hiding me?

so me and my boyfriend have been dating for five months and things were moving pretty quickly and getting serious really fast. He’s really sweet guy. A gentleman. I have not met his family. Yet he claims they know about me. at first he told me that his parents thinks that he’s sleeping over at a friends house, and I got very upset with him, and I told him to tell his mom the truth because I wasn’t going to tolerate that. He did take me over to his house once his mother was actually out of town and his father was home, but his father didn’t know it was in the house. He asked me if I wanted to meet him but he made it seem like it would make his dad feel caught off guard and of course me feeling otherwise I said no. Fast forwarding couple months I found out I was pregnant and I told him he was shocked at first, but he was happy. He said we can have a baby shower at a hall and I was wondering, where were we going to get the money from to do it at a hall and he painted this picture of His family helping out my family helping out so I agree to it. I asked him. When will you be telling your mom? He told me that he would tell her when I get to my second trimester. I’m in my second trimester and he hasn’t told his mom yet. I brought it to his attention, and he told me that this does not concern her and got a bit upset,. is he afraid to tell his mom or is he just hiding me?

Update: when i spoke to him about this for the last time he told me this has nothing to do with his mother and that his son’s mother inlaw is sick and about to pass and his mom is stressed out and he doesn’t want his mom to stress. Isn’t the new edition to the family supposed to ease a bit of that stress and tension?
