This could be a happy birthday 🎈

On my upcoming birthday, I had hoped for you to be with me. We could go on a date and spend the entire day together. I mentioned that I was ready to meet up in October. However, it seems you have other plans.

You mentioned that one of your colleagues will be joining you, and he got permission from his wife. But I'm your girlfriend, and you didn't consult with me before making this decision.

I've never stopped you from going anywhere, but it would have meant a lot if you had discussed this with me.

I understand that if I bring this up, you might say "I refused to meet you everytime you ask".

However, it would have made my birthday truly special if you had considered meeting me.

You might try to meet me as soon as you return, but all I wanted was for you to be here on my birthday.
