This is a long story so please bear with me, as i want you to know the full story,

this all started just over 1 year ago. My daughter was going out with a guy for 4 years who my self and all of our family got on with really well until my daughter rang us one night to help her as her partner had hit her and she had to locked herself in the bathroom. I went up to their house to help her and had to call the police . My daughter moved in with me and her step dad whom she got on with really well. My other daughters supported their sister and gave her help when she was taking her ex partner to court. A few months later we where told by my daughters ex partner that she had been having an affair with someone else which i asked my daughter about and she denied for some time and then finally admitted it to us. My father then took seriously ill and died within a few weeks and at this time my daughter and ex partner got back together. she then she started to become distant with all of her family and told us that she just wanted space to sort things out with her partner which we said we would give her. Her partner also stated that he wanted nothing to do with us because we helped her when she asked for our help and that we should not have got involved. Both of them then decided to move to another country and she promised to keep in touch. Since she left she has never rang, we have always been the ones to ring her and she has been very dry on the phone. they returned home to visit 6 months ago and stayed with one of my sisters who does not speak to any of our family either, i got to see her for 10 mins on my own and asked her what we had done to be treated like this and she said "nothing" . I asked her to keep in touch more often and wished her all the best . I hardly heard from her and she was again dry every time i called her. Again at christmas they came over and stayed with my sister and when i went to meet her on christmas eveshe was with my sister and would not come with me for lunch on her own so i could not get a chance to talk to her . I rang her to arrange to meet with her on my own before she left and she started shouting at me on the phone and being abusive stating that when she came over i always spoiled her visit because I wanted to meet her on my own to spend some time with her. I did not shout or roar back, she had me in tears and I begged her to tell me what i done on her and she just kept saying ,,,nothing. I sent her a text the day before she left to go back home to see if she would meet me to say goodby and i have had no reply. I then texed and tried to ring her to see if she got back home safe and no reply. I am so confused by her beheivour as she has cut out her 3 sisters also who have done nothing on her. I just kont know how to deal with this anymore . I wish I knew what we all have done so we can put it right but she wont talk to any of us. I have had so many sleepless nitghts and never new what panic attacks where until now. Thanks for listening !!
