To be absolutely gutted about this

[Rhian90]

I decided to end my 20 year relationship a few months ago as he was just lazy and uninterested in family life. We have 2 children age 4 and 7. 3 weeks after the split I found out he was taking the children out with another woman and her child (she is a single mum) he only has them one night per week and although I admit I am a bit bitter, shouldn’t they be spending quality time with him instead?

I will get over this won’t I?

Where does it say she's a "new partner"?

The kids say she’s sleeping over.

@Rhian90, yes you will get over it by reminding yourself why you broke up with him in the first place. You'll have a better relationship with the kids than him and they'll help you through.

It’s just so bizarre how a person can change so much

Everything is still raw. Do you have close friends/family to vent to?

Are you married? What will child arrangements look like post divorce if you are married? What about money arrangements?

Some men don’t see women as life long partners. They look for greener grass elsewhere. He probably knew this women and has swapped you for her somewhat readily. Totally sucks of course. As he wasn’t engaging in family life with you before you split, he’s not likely to step up now after you ended the relationship. Lots of men don’t do more when single if they didn’t do much when in a relationship. He’s just found another comfort blanket.

I did it put it to him and he said ‘we are spending loads of quality time thanks’

Thanks

Not entirely sure it’s the role of young DC to help mum. They won’t be happy either!

As they aren’t married I’m assuming OP cannot expect much from ex.
