I say this kindly, but I think you're being self-centered and probably unrealistic. You want him to express his feelings for you the same way you express your feelings for him. Rather than asking him to change to suit you, consider asking him how HE expresses his feelings. Maybe to him it's a matter of being steady and being there for you every day even when he's tired or busy. Maybe it's him changing the spark plugs in your car. Or whatever. He may be expressing his feelings for you in many positive ways that you just don't recognize. Ask him with an open mind and really listen to his answers.

I can tell you that my sister's husband is one of the LEAST romantic guys I have ever met. He doesn't like public displays of affection. He almost never buys birthday gifts, he buys lousy Christmas presents, and I don't think he has ever written my sister a cutesy note in his life. But he is rock steady and he loves my sister. He makes her laugh. He works hard to provide for their family. He coaches the kids' soccer teams. He shovels the driveway and does the laundry. He expresses his love in his own way. Maybe your boyfriend is the same? Maybe he is expressing his feelings for you in a hundred different ways but you just don't see them?
