I've recently started attending a new exercise class in my local town, there I've made friends with a few of the other ladies. We're not friends really outside of the class.but do have general chatter when there and sometimes talk through social media etc. This group of ladies all have children who go to school together so talk while they are dropping/picking children up so naturally they are closer to each other and occasionally go for drinks together. Recently I bumped into a few of them while out for a night with my OH and a few of our friends. It was obvious that one of the ladies in particular had had a bit too much to drink and started telling me how she thought she and I didn't "click" and how she didn't really like me and we could never really get along. I'm not too bothered about that, and apparently she's told a few of the other ladies how she doesn't like talking to me and doesn't think we "click." What I am bothered about is that she obviously doesn't remember telling me this as she has been randomly messaging me to start conversations on social media and via text, especially when it might appear like something bad has happened such as when my OH deleted Facebook because he prefers Twitter so was no longer appearing as my partner on my page.
I just think there's something wrong with a person who tells everyone they don't like someone but then secretly tries to talk to them, strikes me as bitchy and two faced. I'm always polite and will talk with her, I'll talk to anyone really unless they have been very unpleasant but Aibu to be extremely weary around this woman?
