Normal Age to Move Out?

So I just turned 20 yesterday, and I’ll have my Associates in Science this May. I plan to go on to get a Bachelors in Construction Management (online) in the fall of this year, but I’m still living at home. I work full time and make $10.50 an hour. This gives me about $620 every two weeks, but I have car insurance, a car payment, college payments, and a phone plan. I’m not completely broke because I’ve been saving money, but I really just want to move out. I have no idea where to start. My boyfriend, we’re planning on getting married, but we don’t want to buy a house because we aren’t sure where our future jobs will be just yet. I make more than he does at the moment, and he’s in the same situation as I am. I just don’t know when the appropriate age to move out is?? I want to now, but we don’t make enough!! Is there any advice anyone can give me?
