People who use shock collars (or any other cruel methods) on animals are not going to be my friends and I am not even a pet person.

As about friendship it sounds that she was ok with chit chat online on social media but wasn’t up to anything like actual hanging out let alone being actual friends. She had no interest in you actually visiting them (was she the one inviting you first or you were the one suggesting you visit them?). Her way to get out of it was telling you she is too busy. I am not excusing her but hosting people from out of town or even just show them around if they stay in the hotel is a lot of work. And if you only met once, she might not be very invested

It sounds that perhaps it wasn’t as true friendship as you thought it was or hoped it would be. But frankly if she is so nasty and doesn’t even share same views why even be friends with her. Good riddance.

I missed where she told you how great her husband is. Lol who cares. Weirdo. Like what’s the use for you to know how great is her husband if you don’t ever spend time together.
