Are you an introvert extrovert or ambivert

I'm an extreme introvert married to an extrovert and I give off a social outgoing impression (I've been told) but I am very much an introvert and so it confuses people I wish I was an extrovert so that ide keep my friends happy answering phone calls more than I like to and socializing more but I dread those things lol. I love my close close friends but I'm a total homebody anybody relate? I have a lot of extroverted friends and its draining I always feel like I'm letting them down but I've lately come to accept myself the way I am and asert myself with what works for me and what doesnt but I sure wish it'd be easier 😏 I'm an infj. Tia for participating!
