Child maintenance Ireland?

Hi guys. I’m a mom of 3. My “partner” is the biological father of two of my kids, he’s taken my oldest child as his own since day one of being together. We have drifted far far apart and honestly him being a emotionally unavailable and toxic person who upsets me all the time without taking responsibility is playing a big part on my mental health, I am fed up and I’ve had enough. It’s not good for me nor is it good for my kids, he’s not abusive physically but has no problem putting me down mentally which is something my children get to witness as he has no self control and thinks “sorry” will fix everything. I was wondering what is the child maintance amount per child in Ireland? Is it paid weekly? He doesn’t really help around the house and for the last while I’ve been doing EVERYTHING so I’m not worried about not having help with that. We currently live together and I’m worried I won’t be able to pay rent on my own without his financial help. But how much are people really getting? Is it like 50€ per child a month?
