OP,
I really agree with the poster's who think he has been very manipulative.
I know what I like.
You told him what you like.
He changed it and let you go on thinking you were getting what you liked for it to pulled out from under you.
You will never forget your 40th alright. For all the wrong reasons.
He is arrogant and disrespectful of you.
You don't do what he did and respect the person you are with.
I really feel for you.
In your place I probably would have a cry and want to really lash out in pure temper.
Now he's told you a week before because there is a lot of organising to be done for everyone and he certainly doesn't want to do that.
I know that I would not forget this and I would be having a very hard think about him.
I don't like being messed with and he has hugely messed with you.
Oh and him welling up would only piss me off. Manipulative.
Your parents not filling you in is also weird.
Big wake up call.
My advice is see how he behaves this weekend. If he kills himself organising everything re food etc. things may, just may be salvageable.
However, if he is expecting you to take over now and organise it all I would absolutely believe you are in a rotten relationship and he is neither a nice or good man.
Happy birthday OP💐
