I text her a couple of weeks ago asking about meeting up (live in different towns) and we said we'd go and get our nails done together sometime in the next few weeks.
I've just looked on Instagram and seen she's uploaded a picture of her new nails which she's had done, I commented "Oh I thought we were going to get them done together", and she replied "We never arranged a date and you do things and don't invite me" 
I know she's getting at the fact I've been meeting with a few new friends and no I haven't invited her. But really?
