He doesn't help me!!.

Penny
I'v been with my other half for almost 2 years now, he had a job when I met him the after a few weeks of been together he left & hasn't had a job since!. I have 3 children from my last relationship & im due for my 4th in 3 months I have PGP really bad & can't do that much around the house & my other half doesn't help me what so ever! He's always been lazy & never helped me out that much but lately he's getting really sloppy he says he's going to change but everyday is the same. I'v told him I'll leave him if he doesn't start helping or help me buy for our baby as I'm buy everything & paying all the bills!. 
Help What Do I Do???
