Romantic potential or no? After 3 years of being called his golf wife and he takes me out on my birthday?

More deets - he is my upstairs neighbor, our assigned parking spots are next to each other, our kids are close in age, I'm three years older than him (we're in our 50s, both divorced), and we've been in a golf buddy situationship for 3+ years (he calls me his golf wife). We're busy with work and family lives, but golf together during the season (on a couples pass because it's cheaper), occasionally grab a nice dinner and wine together, he goes all out on my bday. I ❤ have feelings for him. Help.
