His stroppy kids are hard work and ruin everything

I'M a woman in my 30s and have been with my partner for nearly a year but we don't live together.

- 

We both have two kids each from our previous relationships, who are a similar age.

My problem is, his are extremely hard work and my kids really don't like them. They're loud, they don't share, they're mean, they throw epic tantrums and don't have any boundaries. They play their parents off against each other and my partner is too soft with them.

I do feel sorry for them, as their mum is a nightmare, but I have to think about my own kids too.

We tend to see my partner's children every other weekend when they stay with him, and last time we left early to come home because they were so badly behaved.
