AITAH for hanging up on my boyfriend?

We recently have been talking about our future and he’s (M24)been unhappy with me (F21)because I always said I don’t want to have kids until 30 and he is upset I’m not willing to compromise on that. He recently told me he is willing to wait 4 years to which I said “I would only be 35!” He then told me “you are fucking 21. It’s time to fucking act like it. You’re a grown ass adult and instead of this you are choosing to sleep around?” I was extremely hurt and instantly started crying because I think I am mature for my age, I just have goals to finish. I also would never sleep around so that accusation hurt. After this I said “how could you say that?” And he acted like he didn’t say anything wrong. I then said “I would never do that. Watch your fucking mouth. I’ll talk to you later” and hung up. Was it wrong of me to hang up instead of talking it through? I just want to go into the future discussion (he hasn’t contacted me in an hour since the call) with a clear head and understanding of the situation from another POV. Thanks
