Hello again Katylove.

I'm wondering why you wouldnt text/call to say you couldnt make it?

My guess is your colleague is a miffed at being let down with no warning.

If you're withdrawing because you don't like her vibe then why would you expect or be bothered about her non response?

If you don't trust her or think that she's interested in you enough to be a good friend then I think you're at the point where you can heave a sigh of relief...she's taken the hint.  Now you can go to your fitness classes and enjoy it 

I bet you feel more relieved than hurt though   

Did you not contact your friend to tell them you couldn't make it? A text?

Hi Katylove ..welcome Sounds to me like your friendship might have run its course ....maybe time to let it go . 

I'd think anybody would naturally text to say they couldn't make it?   that's just common courtesty is it not?      Cosi's right though- the friendship's toast, so heave a sigh or relief and move on...

Maybe she thought you were ill and didn't like to bother you, maybe she was miffed you hadn't let her know you were not going to turn up. Seriously, I would have thought the text or call should have been coming from your direction and not the other way around ...and I agree with the others, it's time to call it a day.
