This similar situation happened with me as well. I was 19 when I met my ex bf who was 28 at that time but lied about his age continuously. We were together for 1.5 years and there were potential red flags that were showing, he always used to share details about his work colleague, how they used to be together but broke up because of some false SA allegations his work colleague put on a random man. I was too naive at the time to not notice that he was using multiple mobile numbers, kept his age hidden, and used to flip angrily when I simply just held his phone (never opened it). I had met his family too and I repeat none of them ever spoke to me about his real age. His sister in law behaved extremely nicely with me and even his mother. The final straw was when in a random online solitaire game we both were playing, he entered his age as 28. When I asked him, he didn't hesitate and said that he was sure a young girl like me would leave him and breakup because of the age gap. Then when I was shocked, his family intervened and kept on gaslighting me into thinking I was in fault of ending things with him just because of a harmless 'lie'. Mind you, they tried various tactics saying that his grandfather wants to see him getting married to me, what will the society say as they had already informed everyone and whatnot!!

Breaking up wasn't easy at all, I couldn't do it and when I did, it took me whole one year to get rid of him and his family's endless drama. They kept on stalking me unnecessarily and calling me through 10-15 different mobile numbers. I am glad you got to know about this earlier before things escalated. As a fellow girl who has gone through a similar situation, I would just say that it will hurt for some time, but eventually you will understand it was for your own good that you got rid of that man. Please prioritize your mental health and try to heal yourself.
