Been with my partner 21 years we have 1 twelve year old daughter who has always been very close and clingy to her mum.
On Xmas eve I found out my partner was cheating we had a major row and daughter heard everything so knows her mum is having an affair - I offered to forgive but she didn't want to know and said she didn't love me anymore and wanted to sell the house. OH then tried her best to try and get me to move out of the house but it is financially impractical.
Since then she has given me the silent treatment and is completely ignoring me in the house while we live in separate rooms until its sold.
However the reason for this post is that although my daughter knows her mum is in the wrong she just wants to keep her home and thinks that because I won't move out and continue to pay for everything the house has to be sold, so now she is not talking to me either, ignoring me and wont reply to phone calls or texts like her mum. If I offer to take her anywhere she won't go. She will only talk to me when she wants something. She is now more clingy with her mum than ever and they are both just spending all their time in the bedroom with the door shut.
If I try and talk to daughter she just says "shut up, go away". I've told her that her behaviour is unacceptable but to no avail. Generally she has always been very well behaved , loving and polite.
I feel like I've lost her forever because when the house is sold I will see less of her and she will drift even further away.
What can I do?
