Separated from my H in the summer and did the 'mummy and daddy don't want to be together anymore' thing. I did this because i felt it was the right thing for the DCs - I didn't want them to feel that they had to take one person's side over the other.
It has been hard. Their dad moved out so, on some level, they do feel rejected by him and they take it out on me. I feel rejected too because, in reality, that is what has happened.
All 3 DCs have reacted differently. But they have all taken their feelings out on me. On some level, they all feel, in slightly different ways, that dad has left me, possibly because I was so angry, and if they get angry with him he might leave them too. That said, they are all fiercely protective of me at times and are surprisingly aware of how much I do to keep everything going.
On my good days, I feel quite honoured that the DCs feel safe enough with me to let it all out. (Obviously, on bad days I don't feel so good and want to tell them what an arse their dad is!)
For all of them, I have tried very hard not to criticise their dad, to tell them that we both love them and also to try to talk to them about different types of love and relationship. That the love between a husband and wife is different to that between parent and child. That one relationship can change but the other is forever.
My youngest (6) has been very whiny and wingey and not wanted to go to school. His behaviour has been really irritating. I've been reassuring him, telling him that mum and dad both love him very much. I have been getting him to punch pillows and it is clear that he is very angry.
Finally, I talked to him about how I thought he was feeling, partly based on how I felt when my parents separated when I was 7. That I thought he hated his mum and dad for what they have done and how much what they have done has hurt him.
Young children are very literal and do not distinguish between behaviour and people. A child behaving badly is a 'naughty' child etc etc. So, I think it is difficult when a child of this age sees his parents, who he is programmed very deeply to love, behaving in ways he sees as 'bad'. Is he bad for not loving his parents? If anyone finds out will he be punished for being bad? If he hates his parents and they find out, maybe they will hate him?
I think this is all very scarey for a small child and they don't have the emotional understanding to articulate it either. It's taken me 9 months to finally sit down with my DS and tell him a little of how I think he might be feeling and to reassure him that however he feels about me won't change how I feel about him. That sometimes I will get angry about his behaviour and get cross but that that does not mean that I don't love him and that I will love him forever, whatever he does. That it is okay and normal for him to hate me sometimes and that I am big enough to cope with that and that is why I am the mummy and he is the child.
Sorry so long, sorry you are going through this.
