I have a friend, we are good friends but are drifting somewhat lately.
Anyway, there was a time when her group of closer friends and a group of friends that I am close with were sort of becoming one group. We went away for a weekend, they were always invited to 'my' friends occasions etc, although it has become apparent that it is never reciprocated from 'their' side and we have really separated into 2 groups again. Oh well, not the end of the world. At first I was really stuck in the middle being friends with both sides but it has become apparent that the group that doesn't reciprocate don't include me either so I don't think of them as friends anymore. That's life and I am not bothered as I feel we don't have that much in common.
Now my good friend has a very busy life, she is always doing something and always has to fill all of her time, she can never just go with the flow but she often has the whole month booked in advance of stuff to do.
Recently 'my' group of friends all did a few different things throughout a week, things to which she was invited but never responded (not that uncommon lately). They were not my events to organise so who was invited along had nothing to do with me, like many other things in the group, its not always me that organises them so I do not dictate who is invited (most of the time she actually is invited).
My close friend had a bit of a go at me recently about this particular week. She had a bone to pick with me and kept saying about how she got on her high horse and thought fine that she wasn't included in the activities that week (she saw on facebook that we had been doing things). I told her that she had been invited and that she hadn't responded (the friend who organised the stuff told me before about it). She was adamant and kept on to me about it. This isn't the first time. Eventually she checked her phone and found that, oh yes, she had been invited. Then came out with excuses as to why she hadn't responded but no apology for basically having a go at me.
This keeps happening with her. Most of the time she is invited, occasionally she isn't but she never invites the rest of 'my' group when she does something with her friends and is rarely inviting me these days, yet she is getting increasingly huffy about being left out of something. It always seem to be me who has to hear about it and takes the flak, as it were.
Now I am rubbish at confrontation or indeed pulling anyone up on something and I will do anything to avoid it but I am getting fed up of this now and I am going to have to say something the next time (and it will as there is something coming up in a few weeks that she isn't invited to) she brings it up.
Please help me be tactful and what do I say? All help appreciated for my social ineptitudes.
