Hi supers,
I was in a very similar position to you only this time yesterday!!
I started divorce proceedings in July of this year,
Decree Nisi was granted 21st October on grounds of stbx's UB.
I have 3 children, twins of 7 (boy and girl) and a girl of 4 years. The MH went on the market in September, didn't feel able OR ready to tell kids then about impending divorce(made viewings a nightmare.)
I found it incredibly difficult to remain a normal, reasonably happy, fun, patient mum whilst dealing with the devastation of the breakdown of my marriage. Quite honestly I was petrified of telling my children. How would they react, how would I cope with the guilt?
Thanks to one of my so-called friends (school mum) who found out about my impending divorce through a friend of a friend and subsequently chose to share the news with the rest of the mums at the school gate, I really felt I had no choice but to tell the children. My stbx and myself discussed what we would say to the children (he came home early from work and we rehearsed what exactly we would say.)
Basically we told the children that we had decided to separate, that mummy and daddy still loved each other (lie!) but were not 'in love' with each other, that we would still be friends and that although they would live with mummy they could see daddy whenever they wanted. We explained that as the house would probably not be sold until the middle of next year (who knows!) mummy and daddy would continue to live together so therefore things would not change immediately. We told them that if they had any questions or problems that they wanted to talk through, however silly they thought they were, they could always talk to mummy or daddy.
I rang the children's school too, informing the head teacher (who was lovely) who told me she would inform their teachers, school office etc and keep an eye on them.
My 7 year old girl seems to have accepted the news well, she told me she was sad but that she understood what was happening. My 7 year old son was very quiet, still is. I'm hoping he might talk to his twin sister (if unable to talk to me straightaway) who can reassure him! My 4 year old didn't take it in at all. As I write this, the children (who are in very good spirits) are sitting with me and stbx watching TV about to have our usual Saturday night dinner! No questions so far. I feel soooo relieved I've finally told them. I owe them that much, I can't continue to live a lie.
supers, I know it's scary but try not to be afraid. You will feel so much relief once the children are told. I wouldn't suggest you say anything yet to your children about your stbx'S BF. That can come later.
I wish you the best of luck supers. I'll be thinking of you. My prayers are with you.
Apologies for the v. long post.
Subra
