<human>: Provide a brief overview of the text.

So this has been an issue for a little while now. I am a person that likes to have small group outings from time to time to relieve some stress. Most people in my group of friends are pretty easy-going, but we have one friend that causes a little trouble. I'll refer to her as R. 

Over the past year R has been invited to most of our group outings. The times she did go she'd be a little pouty and not seem to be enjoying herself. Other times she would tell us she is coming and then just never show up. So, after some time, we took this as her not really enjoying hanging out with the group and stopped inviting her to some outings, but then she would make comments under her breath to me about how she's not "apart" of the group. So, I took that as she wanted to be invited again, yet she continued the same behavior as mentioned above. 

Well, in a couple weeks we are taking a small road trip to a fair. I told her about it and invited her to join us. Recently, My SO made a group message to try and see who's all going and who can give rides etc. 

Well, she R just responds her and her SO are going, but not to the fair.Leading up to that moment, she had been saying she was interested in going to the fair.  I mean, the whole point of this trip will be the fair. We are going to be there all day and won't have time to going any where else. I don't know. Is it crazy to find this rude? 

I don't think it would have bothered me so much if she had just said that she is not going. 

Now this is kind of the final straw for me, but I also don't want to be mean. So, am I crazy for being bothered by the whole event scenario and would it be mean not to invite her to events anymore?
<bot>: Have tried to invite friend to group outings, but ether pouts the whole time or doesn't go. Is it mean to just stop inviting her to group outings?
