What should I do please ?
My cousin and i have been fairly close over the years see each other once a year to go clubbing or cinema , and see each other at family events we do not live nearby to each other . last summer I invited her and her daughter on a trip along with my sis in law and all our kids . One eve She proceeded to drink two bottles of prosecco and then laid into me about my abilities in my profession telling my sis in law all the reasons why, i stood up to her but she wouldn't let it go ridiculing and laughing at me aided by drunkeness . I got quite angry and vocal in my defence she stopped , we all.went to bed and never spoke of it again .
I invited her to my birthday party ( milestone bday ) she sent a strange txt saying she wasnt sure if she was freind or foe and then didn't come . So far I am.prepared to put it to one side , however the last straw is that she has now told our aunt's and uncles that I am not talking to her obviously painting me in a bad light , which I am very upset about
advice please :
a) move on rise above her nastiness
b) challenge her once again and risk permanent damage to.our relationship and more fuel for her to be unkind about me to relatives
c) call my relatives and give my side of this

When she sent the text asking if she was friend or foe did you respond and if so what did you say?

You know what they say, you can't choose your relatives, but you can choose your friends.
You can, however, choose to cut toxic relationships out of your life.
I'd have nothing more to do with her. I wouldn't get the family involved as the whole thing will escalate.
She sounds about 8.

i sent back this. !?
then when her friend who was invited so in the same chat asked if they could stay over i.said no room ( there wasnt my brother and family staying and house not big enough ) .
assuming as others did that they could book b&b they are not short of cash , both have husbands on high incomes.

Well you've already tried A by inviting her to your party but she ignored that .
If you give your side to relatives in my experience as similar has happened to me they might not want to know . So block ignore and move on .

Ignore

Have you spoken to her since that text? If not then she isn't wrong in what she is saying. However as you did respond (even if quite vaguely) it was up to her to follow it up. You have 2 options.. Do nothing, ignore her telling the family her version or ask her why she said it?

Just call her and have it out. Only way you'll mend things - if you want to that is.

I think then that she’s assuming you’re not talking to her op due to your response. If you are then just clear it up, don’t make it worse.

I tend to steer clear of challenging relationships. Life's too short.

Thanks all who have taken the time to respond . I know that this is an insignificant issue compared to everything else we have going wrong in the world :-( at the mo.
But this is an ongoing issue for me and your advice has really helped , I've now worked out how to go forward
So Thanks Again .
