Unsupportive bf rant

I had our beautiful daughter 5 days ago, and I have 3 prior children here and my oldest at his grandmothers for the summer. Every since I had my daughter he has been in and out. He stayed at the hospital one out of the two days I was there...he never took time off work to help with the kids...and when he is off he works after hours. He had two prior kids from his previous marriage, their preteens and doesn't like to listen to me...simply because he doesn't reinforce that I'm in charge when he is gone and his ex wife told them not to respect me...I been with him for 4 years and he has cheated the last 2 years. Our anniversary is in 3 days and I just found out he has been cheating recently before I gave birth. Obviously I'm still with the jack ass but that's only until I can get us out of here, he acts like he never done anything wrong and doesn't like to talk about it. Then on top of lol this bullshit, his grandmother died and the funeral is tomorrow, with the addition that his kids will be here this weekend. A total of 8 people in a 3 bedroom 2 bath apartment. He isn't going to take the kids with him to the funeral and he wasn't going to tell me he was going to leave them here with me. I'm pissed, for 1. I just had a newborn and is still healing from that...I have a 1 year old who is still trying to adapt to this all and is SUPER NEEDY NOW 2. He hasn't tried to help me with any of this far as cleaning, cooking, letting me rest or even trying to comfort Me. I broke down today because I can't do this, he hasn't made the time to take off work or even be PRESENT!!!! Like now he is getting a freaking hair cut while im here with the kids, then he said he was going to get high with somebody!!! He been at work all freaking day and he works at our freaking apartment!!! I'm sick of this shit because it seems like he for one doesn't respect me or even care that this is taking its toll on me!!! I'm not trying to be a bitch but when is the help going to come in!!! He said his job won't give him paternity leave...actually they do because I asked but he opted not to take it!!! Again WTF!!?! Then I find out one of the bitches he been seeing stay over here!!! And she has a man and a family!! I'm just disgusted and embarrassed!!! He won't answer my calls now because I hung up on him after he told me he was leaving the kids here!!! He said I don't have to feed them or cook for them because they can do that alone!!! Ummm you forgot dumb ass that the food they are eating is the food I PAID for!!! They can get for my whole family!! They are greedy and disrespectful like him!!! I'm trying to ignore this bullshit until I leave but this sorry piece of shit doesn't even care!!! IM DONE!!!!

I DONT HAVE FAMILY TO GO TOO, BEING WITH HIM MADE MY FAMILY AND FRIENDS TURN THEIR HEADS TO ME!!!!
