Rejections

So my oldest is eloping.  Went from we are going to talk to her parents and her church leader one more time to forget it we are just doing this.  Sigh.
My friend didn't show up for our walk yesterday and still haven't heard from her.  Tried text and email.  Saw she was posting on facebook last night so no idea what happened.
And today was a meeting of the group I belong to that someone posted they don't care if I belong to it anymore.  I did not go.  My oldest and his girl did,  so cheated out of time with them.  Cried when they left.  Tried not to, but so upset that these people I thought were friends are basically throwing me out of the group and don't care.  I know it isn't all of them, but couldn't face the ones who are like so if "she doesn't come anymore that doesn't matter.  we will get some new people".
I never seem to get along with anyone for long.  Probably said or did something to make them not like me like I always do.  Sad thing is I never know what happened.  I have had at least 4 people in my life just suddenly cut off all connections with me without any explanation.  They just stop talking to me one day or flat out tell me they don't want to see me any more, but not a one has ever said why.
