AITA for dropping my BF off at my parents and saying “he’s your son now” and walking away?

I was raised by very very strict parents who found flaws in everything I did and at the time when I mentioned that I was tired and wanted them to back off they got angry and yelled at me for being disrespectful. <br><br>After I moved out a few months ago they did a complete 180 and started telling me I was the greatest and most successful person in the world and that they’ve always been supportive. <br><br>I wasn’t under any illusions that they would stay like this for long and now that I’m seeing someone I just knew they would get on his case and find flaws in him. <br><br>They were respectful when they met and for the first few weeks of me introducing him to the extended family but all of that ended at my cousins wedding when they spent the entire night telling my BF that he was a loser for pursuing a degree in information assurance. <br><br>My BF has been pissed and has said that he doesn’t plan on meeting them again and I can’t really blame him. <br><br>However they’ve been blowing up my phone crying about how I’m not letting them see their “son in law” and how I’m keeping him away. <br><br>I had enough of this today and I decided to drop him off at their house and when they opened the door I said “he’s your son now” and walked away. <br><br>Was this immature of me?
