Heartfelt Birthday Message Needed

I’d like a short, heartfelt birthday message written for my boyfriend. It should feel genuine and romantic without sounding exaggerated—something he can read once and remember all day. A warm opening line, a personal touch that celebrates our relationship, and a closing that makes him feel loved are all I really need. Around a single paragraph or so is perfect; no lengthy letter required. If you can weave in subtle birthday wishes while highlighting what makes him special to me, that’s exactly what I’m after.
