Not quite your boyfriend, but more than a “who’s this?” text — welcome to the grey area of modern dating. If you’re somewhere between late-night memes and “should we talk about us?”, yep, you’re probably in a situationship. And birthdays in this zone? Awkward but also kind of perfect. It’s your chance to be sweet, flirty, and funny without overstepping or playing it too cool.
You’re not writing a love letter, but a dry “HBD” won’t cut it either. The right birthday wish lands in that middle ground — thoughtful enough to mean something, casual enough to keep things chill. Below, you’ll find birthday wishes for situationship vibes in all their messy glory. Use them to text the guy you’re dating without making it weird.

Conclusion:
Situationships are messy. Birthday wishes don’t have to be. The right message lets you stay true to whatever undefined, delightfully confusing thing you two are — whether that’s flirty, sarcastic, or full-on “what even is this?” energy. A funny wish can land better than a serious one because it shows you get it — the humor, the tension, the not-so-subtle chaos.
So go ahead and send that text, drop that DM, or scribble it into a card you bought last minute. Make him laugh, keep him guessing, and enjoy the weird little romance.
