To think I should say something?

[StellaArquatre]

Long story short, one of my best friends (A) can be a little petulant sometimes. Recent incident occurred when I agreed to see our other mutual friend and another, less close friend letting A know. I didn't invite her explicitly as she was working and couldn't have made it. She blanked me for a week and was funny with me for weeks after! (Normally she is nice and we do get on very well!)

A knows I am up to the gills with work at the moment but held a bday celebration for mutual friend last night - not inviting me or letting me know. I couldn't have gone but was annoyed to find out from others. Normally wouldn't care as would have assumed she knew I was busy (she does) but just seems ridiculous given how sensitive she is about these things!

I messaged her this morn asking about last night and she was effusive in thanking me for something else so assume she feels a bit guilty. Am I being over sensitive? Should I say something more direct?

Be direct

Well, you're Even Stevens now, aren't you?

I invite people to events, even if I know they can't/won't come. It's nice.

I agree with @MaidOfStars

Well what did you expect.
You deliberately never invited A. Whether she could make or not. She still could have been asked. Its not nice being excluded is it, in your case a taste of your own medicine.

So hang on, you didn't invite her because she couldn't go and you don't understand why she's pissed as you think it's fine , and she didn't invite you because you couldn't go and you're now pissed and don't think that's fine. She just did the exact same back to you as you did to her and you don't like it?

Okdoke

If you can't take it, you shouldn't dish it out.

Hopefully you've learnt from this.

'I didn't invite her explicitly as she was working and couldn't have made it'.

'I couldn't have gone but was annoyed to find out from others'.

Get it?

I pressed send too soon! We had a massive talk when I did it, I apologised, it was very spur of the moment -but importantly I apologised and agreed never to do it again/saw why she might be hurt. She has done the reverse a few times now. Obviously to punish me. I am not a petty person and would always give a friend the benefit of the doubt but since she kicked off at me and then has done the same, it just seems malicious? Does this make sense?

I guess you could tell her " hey A, we are even-stevens now. If you pull another one, I am demoting you to tier-2"
Yes, she is being vindictive.

Also the difference is i did let A know I was going beforehand. She would have known she was invited. Didn't hear a single thing from A about it this time.

Whats good for the goose....

You both sound as bad as each other.
