This is about someone who up until very recently was considered my best friend, I'll try and keep as short as possible.
The thing that is particularly sticking in my mind is a comment that she made to me about my DC. Our DCs had started an activity together a couple of years ago and to me they all seemed the same ability wise with it. Then there was a period where none of them were progressing and we looked into it. Through that and other circumstances they ended up doing it separately. Within 2 weeks my DC had really excelled and is continuing to do well. Friends DC has not progressed at all and is at the same point that they were a year ago. At one point my DC said they may have wanted to do it more seriously in the future. I was telling my friend this (who has a real 'thing' about the fact that my DC has progressed where hers hasn't) who then said "well if X (my DC) had a natural ability they would have shown it by now" (we are talking about a just turned 5 year old btw).
I am known for being outspoken but when it comes to actual confrontation I say absolutely nothing because I can't bear it to the point where I shake, heart pounds and I can't get my words out. So I said nothing when she said this. I have been dwelling on it for a while. I KNOW she would not have put up with a comment like this from me, nor would I have said it in the first place.
Recently she was talking to me on a rare occasion that I actually saw her and mid conversation she said "I have a bone to pick with you" then had a go at me about outings that I been on with friends where she said she hadn't been invited. I told her that she had but she hadn't replied to the organiser, a mutual friend. She was adamant. Then she bothered to check her phone where she saw that I was right, she had been invited, then came out with her usual 'oh I'm so incredibly busy I don't have 30 seconds to send a text' excuses. She is a very busy person but isn't everyone. Again I said nothing. There was no hint of an apology from her.
I invited her to something that we were all doing recently and she was the only 1 not to reply. I assumed she wasn't coming. She phoned me half an hour before to confirm details. I said I didn't think she was coming as I hadn't had a reply, she was adamant she had replied. I checked my phone and there was no reply, so she blamed the network, all other texts from friends came through to me no problem.
She makes snippy comments if she isn't invited to something but she isn't really as good friends with the group any more, she has more broken off with her own group but still expects to be invited to everything but she doesn't invite any of us with her friends. We don't care but she seems to be making an issue of it every time. She has even told me on more than 1 occasion that she doesn't care if she ever saw the group I am friends with again and doesn't really have anything in common with them (they don't know she has said this), so I am at a loss as to why she cares, but she seems to care a lot about being left out.
She has also made a few comments to me that has made me 
about others, about being thick etc. Another good friend of mine has also told me of a couple of things she has said to her before, like "aren't you a bit young to be having all these kids?" when she had 2 at the age of 25 and was discussing the possibility of another in the future and she told her that she didn't know what busy was when they were talking about stuff they had been up to. The (ex?) best friend tells everyone about all the things she is doing but doesn't seem interested in others. She asked the friend above what she has been up to after prattling on about herself and when my friend was replying, she just walked off! This friend has never said much to me about her before as we were close but it is apparent that she doesn't like her and I don't blame her.
I am getting fed up but this friend is coming to the end of her training soon and is going to available to get together. I feel like I am suppose to be suddenly excited, I am not.
Am I overreacting to petty stuff? I feel I am but would like some outside perspective. This friend has been willing to lend me money before which shows she does think a lot of me but recently, I don't know, I feel she is changing since doing her course and I am not sure I have time for her anymore. There are a couple of events coming up in the next few weeks where she is going to be there. I am not going to be able to avoid her.
Sorry for the length and I appreciate any answers.
