Organised a surprise party for DP's birthday on Friday, about 50 people invited.
Told everyone to be at venue for 7pm, all organised. Told him we're going out for a meal, just the two of us.
His DM has just emailed me confused to say she's spoken to DP and he's said we're going for a meal on Friday "so is his party still on or have you cancelled it?"
Oh, and she emailed this to an email address we both use, with the subject title DP's name 
So of course, he's read it but is pretending he hasn't. I'm so upset I could cry.
