There’s 2 points to this.
Firstly, it’s your birthday. From your suggestions, it’s very obvious that you want to get away for a few days. He’s blatantly ignoring that.
and secondly, he’s reminding me of my ex. It’s okay to go away to go see his friends but it’s your birthday and it’s all too much trouble and too expensive?
I’d say make him cry one last time by dumping him OP. You could do better.
