My two closest friends have been gradually excluding me more and more a few times, I've heard them making plans to get together that don't include me. I've also realised they don't use our group WhatsApp (for the 3 of us) as much, instead they message each other directly.
Tonight, we were sat at the same table, and they were making plans to go walking together tomorrow in front of me. We've always gone walking all together. So I said "Oh, you're planning on meeting up tomorrow? That's nice". They clammed up and said they didn't think I'd want to come.
Later on, one friend had left, so I said to the other "I'd like to come walking tomorrow, let me know when you're going". She said she would.
Now I'm thinking I don't actually want to go. I wasn't invited. They were deliberately excluding me.
So - do I just politely decline tomorrow. Or do I say "nah, I don't want to come when I wasn't invited".
How do I come out of this as the better person?
