Lack of financial help from baby dad

Boyfriend has a 9 year old with another women...

He pays her $300 a month..

He doesn’t help me w bills or anything. States he will pay me child support, yet is 7 months behind.. BUT completely caught up for his daughter... he lives w me and our 2 babies and his daughter lives in my house every fri-Sunday....

He just bought her a laptop for Christmas and her mom got her an iPhone around2 months ago.

She lost the iPhone and broke her laptop.

Her mom asked him to replace both he immediately said yes...........

Lied to me said he Never bought her a new iPhone 11 (yes he did).

I don’t understand why he throws alllllll his money at his daughter who we have just as much if not more then her mom. We have 2 babies and he’s not financially helping me at all!!!! Yet when his baby momma asks for money he sends it. When I do he ignores me

..

I guess I should add... we never filed for child support. He just never helped w bills (claims it’s Bc it’s my house ) so when baby came he was giving me the same $300 his daughter was getting... but baby number 2 is here now. And he’s missed 8 months of giving me anything..
