So I have a few friends, two used to be my best friends but then they got closer and are best friends now, (They met thru me) which is fine, i don't mind that their friends but we all have another 2 mutual friends(who r good friends with each other) and I contacted the two mutual Friends to catch up in a group message, 1 replied and we r going next week. But the other one didn't reply to the group but has seen it and also didn't reply to one of my private messages from earlier. Then tonight the one who didn't reply is having a girls night with my old two Friends. Our other mutual friend left the group I created, I'm just wondering why the mutual friend is being strange not replying. I mean it's ok to be with other friends but why ignore me? I think something happened. What do you guys think. I feel like I don't really have any close friends which I don't mind i hope to find some cool people that don't do these weird clicky things

Any advice is appreciated xx
