I am feeling very upset by my partner, am I wrong to feel this way after I feel like he has lied to me?

My partner told me recently that someone he was dating previously had been introduced to his family after they had only been together for a couple of months. We are supposedly supposed to be in an actual relationship, and I haven't met them. what has annoyed me even more is he made such a huge deal about it usually taking him a long time an introduction. I am now feeling like I can't trust him as he clearly hasn't been honest. Does anyone have any advice, please? Thank you
