Ex bestfriend

So the past few weeks we have been messaging but tbh I hadn’t got over what she had done to me so I kinda kept pushing her away with my words hoping she would just walk away… sadly she hasn’t.

So there’s an event me and her use to go to and I said about it and she said she was going which I was like oh ok baring in mind we Havant seen each other for a year and 4 months.

I had time to think about it and said I wouldn’t be going into which she said she also wouldn’t be going as she now had her granddaughter.

So I was like well I will go as I know she won’t be going and made plans with my friends to meet them up town only to find out my ex bestfriend has decided to go as well with the granddaughter.

I can’t cancel my plans just because she is now deciding to go and I do wonder why she is adamant she wants to see me but tomo will be a test as to what true energy is between us now.
