Not sure how to handle this??? long... LOL

ok so the other day i put a post up about how - someone i know is sending me a STD - but i have no intentions on going to her wedding or inviting her to mine.....

I firmly decided that im just NOT inviting her, and if the topic gets brought up, ill casually change the subject and just say 'oh i cant make it'

But in any case... i chat with her online all the time, just small talk - wedding talk etc.....

Today she says to me 'You should be getting your STD today' So i play stupid and say 'really? i didnt think we were invited'
She says 'OF course silly'
SO then i just got quiet.... so then a few mins later, shes like 'SO you better save the date of october 22, 2011 - u better be there' I simply say 'Oh man, I already know FH is working that night'
She then says 'Thats ok, you can come with Jessica and Ill put you at a fun table'

So now im like.... WTTTTF!!!

So again i get quiet!

And then she made a comment like 'ya know it would really mean a lot to me if you guys were there'

I didnt even KNOW how to respond to that one!

Im not the type to come out and say 'IM NOT COMING' or be mean -

Now #1 - I stopped hanging out and talking to her after i sent her and her FH a $75 cookie engagement basket and got a 'thank u so much' thru TEXT and not even an effin phone call! Her and I didnt even talk online for months after that!

#2 -
we dont hang out, EVER
we dont talk on the phone, we dont ever see eachother!

#3 why is it so important to her that Im there!!!

I dont get it??????

So now, I dont know where to go from here!
I know if we chat again online shes gonna ask if i got the STD

what would you do???
