I’m engaged 🎉 but confused ...

I have been dating this guy for 3 months ... 3 MONTHS. But he treats me so good, I met his family last month & the way he treats his nieces is just precious. Which says a lot about a guy. His relationship with his family is beautiful. I really do see a future with him because I love him. A lot of people are saying it’s TOO SOON. I do agree but I am okay with it. Also I am only 19 & he is 23. I can really see our relationship getting far because he is really hard working & he is ambitious & has a great soul. I am very confident about us but all my family calling to tell me it’s too soon is not really helping.
