I don't know my sister anymore

[Faerieinatoadstool]

this is going to be a long one...!

A couple of years ago:
My sis split up with her 2nd husband. One of her (just finished) 6th formers moved into her house as she said that his parents had kicked him out.
Was very low on money and borrowed (with no intention of paying back) from DM and DB (who has special needs) - a few grand in total

Last year:
she told us she had met someone on line and was flying over to see them.

Later:
She got pregnant, secrectly married new man and moved to other country with him, leaving her 3 children with their dad

Now:
Found out she was sacked from teaching, had an affair with the 6th former (we now don't know who babies dad is), was investigated by police and is taking no responsibility and blaming everyone else but mainly our DM.

She has also taken/sold 3 generations of grandparents wedding rings which are supposed to be passed down the family.

I used to love, respect, admire her and now I just feel that everything she has ever told me or done has been a lie.
I feel anger and grief and don't know how to deal with it - guess I just needed to vent.

She sent me a birthday card like everthing is perfectly normal.

I don't know how to deal with her, her new family and her child

Anyone?

Hey not sure i can be much help but I have problems with my sister also (not for same reasons). I have never liked confrontation but don't know how to deal with the anger I feel for her. I feel terribly guilty for my feelings. She has suffered with anxiety/depression since I was a teenager. She is very critical of herself but also of others. I've tried to reach out to her but she often says she is too busy. I recently had a baby and she gushes about him online bit doesn't make much effort to see him. Sounds awful but I feel like she 'drags me down' when I see her. Feel quite lonely with the baby but don't feel able to confront her as I know how mentally fragile she is. Anyway know its not that similar but don't want u to feel alone. It sounds like ur sister has put u and ur family through alot and u gave the right to be angry.

Good grief. No idea how you deal with that one.

I don't want to upset my neice and nephews by cutting her out and I am worried about her new baby but part of me wants to tell her exactly what sort of person she has become (not that she would take any notice).

What do I do about Christmas? Its our first without her and don't know what she will do

She sounds very impulsive and out of control, does she have mental health issues? (Before anyone jumps on me, I am NOT saying people with mental health problems are bad/awful/scary, I speak from personal experience of impulsive life decisions made on the influence of MH disorders)

I do suspect that she has tbh. Anxiety and depression are in the family (me & dad) but the constant lies are beyond that, I don't even know if she knows what is true anymore.

We used to be so close and everyone used to say how similar we are
