We weren't actually going out, just talking for about 3 months and then I was a dck and left it to fizzle out cause I thought it'd be easier. Didn't talk much after but he sent me a happy birthday text a few months later. A couple months after that, he got back with his ex.
I feel like I should be nice and reciprocate the happy birthday but it feels a bit awkward now he's in a relationship. I don't want it to look like I want him back, but I don't want to appear salty by not saying anything. I see him on nights out sometimes and we have mutual friends, we smile and chat and are polite but not actual buddies anymore.
The biggest problem is what do I even say when I wish him happy birthday, and whether to text/snapchat etc. We had an inside joke of sending emails and ecards but that feels a bit OTT and he probably wouldnt even remember the reference lool. I guess if he's in a new relationship my happy birthday will be so insignificant anyway.
PLZ advise me .
