In my opinion, it is better to just wipe off this friends. He/she is just worry that he/she is not accepted in the whole group. A sincere friends will accept on who you are and in case they found anything that you done is not that right, they will discuss with you silently and not to just give a kind of weird look in the public.

I so feel you my friend this things happen to do many people. It’s just that others don’t talk about it so people don’t see if hear about it often
I must say like you I hate it, NOTE! I have not said i don’t like it. It’s the worst place to be. I don’t like th3 idea of someone inviting me to some place, then you leave me hanging, honestly why did you even think of inviting me when you know you won’t even go a me the time to answer questions or even participate in the conversations that will be going on. I remember there was a time when I was invited to go for a drink by a friend, I remember that i am the one who was driving them to the venue. So when we got there, we all entered the premises and ordered what we wanted. I don’t take alcohol myself but at times once in a while I get to drink a glass of wine.So while we are there chatting away me and my friend notice that out host th3 peraon who invited us out seems to be evading us like we were not together. He kept himself busy with his other friends in other tables, and somehow he behaved like he really on top of things when in the actual sense he was not. Me and my friend knew pretty well that he was going through issues but he tried to make it look like it was no big deal and that really kissed me off. Why show off when you know you can’t keep it up! It’s very sad.
