I'm supposed to be going out with my boyfriend this weekend to a fancy dress Halloween party. I won't know many people there - him and a few of his mates that's all.
I'm feeling really insecure about it
. The expectation is that we will both dress up. He has got his costume sorted, wants me to dress up and he's looking forward to it. I was ok about this until realised what the entertainment is.
There is a beautiful young singer/songwriter performing.
That's something my boyfriend does and he very much admires other people who do it too. I don't normally feel threatened by it and it wouldn't bother me if it weren't for the fancy dress element.
The problem is I am nearly 10 years older than him and slightly overweight and she is about 6 years younger than him, slim and very beautiful. And people who've heard her describe her as 'captivating'. I really don't stand a chance 
She will look amazing in Halloween fancy dress.
I will not.
I'm really fighting the urge to just not go now. I wouldn't expect him not to go. I cant do anything about him looking at her and thinking she's beautiful and sexy. But I dont want to be in the room at the same time.
The 'problem' is that I have aspergers and if I go when I feel anxious, uncomfortable and insecure like this it's likely to trigger a shutdown. I cant stop a shutdown once it's started and I don't like them. It's best to avoid them in the first place.
But I know he will feel let down if I don't go.
I don't know what to do.
