Trying not to be upset :(

My boyfriend is hardworking man. He worked from 6-3 at his job and works his dads business afterward. He’s saving up his money (he makes good money) to take over his dads business. He also wants to buy out one of his dads properties and live there when he moves out on his own. Therefore he’s still living at home. He’s 25! The only time we hang out is in his car and have sex. I’ve never once been to his house and when I ask about it he just says “soon”. I understand he’s trying to save and be responsible but I’m sick of sneaking around like we’re teens! What should I do?
