What do you tell the DC?

[MouseyHousey]

My husband has had an affair. I dont know yet how far it has gone.
To be honest I am still feeling too fragile to write the whole thing down (I found out on Sunday) but I need some practical advice.
What do I tell the DC about him not being at home anymore? He is staying with his parents. I am not going to stop him seeing the DC (2 and 6) but the eldest in particular is not stupid and will realise hes not living with us.
I dont know if our marriage will survive this but even if it does he will not be living in our house for a long time to come. So what can I say that hopefully wont get the DCs worried and upset?
I know many of you have been in the situation where you have found your OH having an affair so please tell me how you explained to your DC

I'd tell them the truth that he has gone to stay with grandparents for a while. Get him to keep in touch with kids either in person or by phone or Skype. I refused to tell any lies to kids when it happened to me but also told them only what they needed to know. My kids quite a bit older than yours but didn't ask that many questions. Your six year old will want to know where her daddy is and will be quite happy with explanation. Might be more difficult to explain why mummy is sad. There is a helpful booklet called something like kids in the middle? that gives simple guidance if you decide to separate.

I agree, always the truth, including about you being sad.

You can say that dad kissed (gave a special kiss?) a girl that was not mum, and mum is very sad and angry with dad and dad went away.

The important bit is to tell them that dad doesn't live there anymore and when they will see him, plus that he loves them very much and will always be their dad.
