I'm never busy for the woman I love. I couldn't imagine going all day without messaging her back. Even if I'm at work I might go a couple hours at most before I reply. I message her everyday, I love you and you're the most beautiful woman in the world. I also message her to have a great day and I'll see her after work.

Might be possible your boyfriend wants some space? Don't judge him by my standards because I go above and beyond for my girlfriend. But I'm bipolar and I do everything for her and surprise her with presents every week just because.

Hang in there. You might talk to your boyfriend about it. Great communication between the 2 of you is greatly important.
