@Sam17062002 , I won't waste time commenting on your 'partner's holiday, as it sounds as insignificant as 🤷🏾♀️.
I will say to you though, that there is more to life than a relationship that makes you miserable.
There's more to life than extending yourself, above and beyond for a man's children. Even more so for ones whose father don't care about you.
There's more to life than wasting away with a man who doesn't love you. And know, he will sleep next to you every night (when he's not off on his solo jollies) and not like/love or care about you.
You are worth more than this man will ever offer you.
You will have more time and emotional energy to are for yourself and your children, when you don't have a bellend sapping your energy.
I know you told someone upthread to leave your children out of it; but they are very much in this circus. Every minute you waste on this person, is time you take away from yourself and from them.
He is also showing his children that he doesn't care as much for them (if at all), as much as he cares for himself. They deserve more.
He is also not committed to your family in the way he should be. He doesn't even wish to help you secure a home for your family. What more do you need him to tell you and show you?
