Me and my ex are not together but have children together. It's pretty amicable but there's not much contact at all really. He has a new partner (about a year or so) who also has two kids.
Due to his work he sees them maybe once a month usually for the day a few hours and occasionally has them over night.
They have coped fairly well but the youngest is still struggling a little bit despite reassurance but feels pushed out now 'he has a new family' especially as they don't see him much. I've explained this is not the case but she is additional needs and doesn't understand yet. I suggested maybe it would be nice when he has our children to occasionally (not every single time) to spend time just them and she (the gf) has flipped and said I'm being ridiculous and that she needs to get used to the idea of him and her family so to speak as naturally he is now around her kids more but that would take away time from them. Youngest is 6 if that makes a difference.
Sorry its long was I bu to suggest this?
