I can only speak for myself, for the separation then yes for me over time, it wasn’t easy but I have come to deal with it, but it still effects both our children.
As for bringing up 2 children on your own, I find it a constant battle!
Everyone’s circumstances are different and for me I have had the added concern’s with the kids regarding medical conditions, mental health & ASD and trying to hold down a full time job, so it hasn’t been plain sailing.
We have good days & bad days like any other family.
I hope you have an easier journey
