How would you handle this?

It’s my birthday. My ex, who is supposed to be one of my best friends, apparently has forgotten. I got a totally unrelated email today discussing some practical matters, but no mention of my birthday. She seemed to require reminding in past years, so I can’t say I’m that surprised.

I am hurt, though. I mean, we were together for two and a half years, you’d think she’d know my birthday? Or that it’s around this time of year? Anyway, I’m wondering how to handle this. Do I mention it, do I let it go? I want to call her on it or at least have her realize she forgot, but I know that may not be that tactful and perhaps not the best solution long-term.

So, my peeps, how would YOU handle it?
