HS sweethearts! When did yall....

When did y'all hs sweet hearts/ younger couple's/ couples that have just been together for a while, move out together? How did you save? I'm 19 he's 20 almost 21 and I feel like we are falling behind our other friends. Some married some pregnant some engaged some just have zero plans in life yet and that's fine too. I just want to move out with him we probably bring in 3000-4000 a month combined so I don't think financially we would struggle to hard but what do you guys think? (I live in Oklahoma if that helps) how did you tell your parents you wanted to move out together?
