My XH left me when our DC were 1 and 3. They are now 18 and soon to be 16 so a fair bit of water under the bridge.
Its tough being a single parent, especially in the early days of finding your routine but it was easier and much better than being an unhappy married one.
My solicitor called it finding the you, from the we.
Its like when you do the food shop and you routinely fill the trolley going up and down the aisles. Buying bits to please everyone. Suddenly, you're the adult to please. The meal choices that are going in the trolley are entirely to suit what you want to put on the table.
My XH didn't like cheese. Hated the smell and made a fuss about it. I remember the realisation I could have a little cheese board again.
I hadn't noticed the erosion of me but I certainly noticed the reawakening. Its a wonderful feeling.
The family routine is all yours in your home. If you want to have Pj's till midday on a Saturday or bath at 4pm and tea infront of a family film every Sunday night, its all yours to own. The special memories are all things you and your DC create together.
I remarried after 3 years and we have a DD now 10.
I managed to make contact with my XH relatives early on and made it clear that they weren't part of the divorce from my point of view and were still welcome to visit and see the DC. I'm really glad I did this. It wasn't an easy thing to do but I think it smoothed the path for the DC. Only mum and dad were moving apart not half the greater family dividing away.
My elder two have always been allowed to talk about what they think about the situation, I've done my damndest to not badmouth XH or over share adult stuff going on, whilst honestly answering questions. I have also stood quite firm over what suits the family unit as the children have lived full time with me.
Not badmouthing doesn't mean I roll over if a change to routine is difficult for us to juggle we state that. If it is do-able we go with it and don't get dragged into ever ongoing negotiations.
We have a routine of access and everyone knows where they stand. XH and I email a couple of times a year and state dates which are potential conflicts and propose variations. We keep contact in writing through email. As I felt pressured by early contact I created a folder in my email that XH emails go to and I'm strict with myself on only accessing this once a week. Very little contact is really urgent.
Looking back I wish I'd divorced sooner but I hadn't realised how little of me was left.
Enjoy finding you.
