Ladies I can't take it anymore!

Me and my husband have been together for almost 5 years. first two years were great but ever since then it's been very rocky and we've been on and off. I have 2 beautiful girls with him and a son on the way. ladies I'm tired, bitchy, aggravated.

I cannot speak with my husband the way I would like to (normal daily convo) every time I try to talk with him about the kids he ignores me and walks away. then he wonders why I get so mad a frustrated and start yelling. NOBODY and I mean NOBODY likes being ignored especially by their husband.

my girls have a lot of energy and they get into and onto everything. when I discipline them and tell them no, he apparently doesn't agree with me. but what he doesn't understand and I've tried telling him multiple times, is they cannot do whatever they want. they need structure and stability and I am the only one putting forth that effort. I'm tired of always being the bitch mom towards my girls but honestly ladies if I don't show them right from wrong, he isn't gonna so there for they're gonna think anything and everything is okay.

I really am losing all my hoping of having a family with him. he does not act like a father should nor does he try. all he wants to do is put on this goody daddy scene and make mommy look bad. I want to tell him so bad that if he can't start acting like a father then I'm gonna have to leave and raise them by myself without him.

sorry so long of a story but I had to let it out somewhere! ladies please give me advice.
