Not sure if this is the right place for this but here goes anyway.
I have a close friend (have been friends for about 9 years I was her bridesmaid and am friends with her whole family) who I am struggling with a bit at the moment. Although we are good friends I feel that we have quite different views on things sometimes. On a few different occasions I have done things which have offended her (unintentionally of course ) and she goes the route of ignoring me for a few days or becoming cold in her responses or most recently cancelling plans we had made, instead of saying 'when you did x it upset me'. I have confronted her on occasions when her behaviour has indicated that she feels I have done something wrong but it is getting wearing feeling like I am walking on eggshells especially when i don't always feel i have done something wrong. An example of something I did wrong is to have not gone to her Dad's birthday party, which was being hosted at her house, when baby DD and I both had a stinking cold. Both felt grotty and was also concerned about passing the cold on to everyone. She had told me not to come if I felt rotten but then behaved in such a way that it was obvious that it was definitely NOT ok. Eventually I asked her about it as I couldn't stand it any longer and she said she thought it was rude that I didn't message her dad personally to let him know (we're not talking small family party here, they are extremely sociable and invited at least 50 people). Although it would never occur to me to be offended over something like that I conceded that I perhaps should have contacted him and immediately messaged him to apologise, but did that really warrant the cold shoulder? Sometimes I feel like there was a big book of social rules that was handed out to everyone but me as I so often seem to get it wrong despite trying to do the right thing.
What can I do to fix my friendship? I just can't handle this being the way things are every time I commit a transgression real or imagined. I have probably made her sound horrible which she really isn't, she's mostly lovely, and her perspective on the subject would no doubt be different, but I am finding this aspect of our friendship so hard.
