So this is complicated so I apologise in advance.
Two years ago I had a big, drunken fall out with one of my best friends. Despite attempts to salvage the friendship it never was resolved.
Now this girl was introduced to my group of friends through me, but was never close to anyone, never saw anyone unless I was there, and never spoke to anyone outside of group social events. A lot of the girls have since admitted they never really liked her.
This ex friend of mine is a very manipulative and since we fell out has done a number of things to try and hurt me. Such as spreading utterly untrue, vicious rumours about things I have supposedly said to try and make me look like a bad person, to inviting my close friend (since school) over for dinner. My friend went and afterwards I spoke to her about it, explained it had upset me and i didn't see why she went as they weren't friends before, so couldn't she see she was being used now to hurt me. My friend agreed and said she had crossed a line, but this girl had been badgering her to see her and she ran out of excuses.
So this afternoon another friend of mine has sent me a photo showing that ALL of my friends went to a bbq at my ex best friends house yesterday and asked me what the fuck was going on? Am i right to be upset? I feel it is really disloyal because 1. They weren't ever friends before 2. They have said they don't like her 3. They know all the poison and hurt this girl has sent my way 4. They've previously admitted that they think a lot of what she does is a 'power play'. I don't understand what reason they have for going? I know i sound very high school, but I can't help how I feel and I just feel really let down.
