How do you deal with petty baby mommas?

So my husband has a baby momma who is petty as ever. She lies through her teeth. And thinks I’m insecure or jealous of her when I just don’t like her bullshit immature personality.

I been with my man over 2 years now and we got married maybe after a year. She hasn’t been with this girl since 2016 a little before when his daughter was born. They basically were together for 4 years. He met her by his now passed brother and moved in with him and his mom and sister at the age of like 18. She got arrested for possession of weed or some shit and my husbands family was there to bail her out, not hers. She didn’t graduate high school but they helped her get her GED. When she was living with them she didn’t work or pay for anything, they took care of her like their own. They moved from NY, to Texas, to Florida where my husband had his daughter. Baby mom was probably like 6-8 months when they started not getting along and she always was jealous of him with working outside of the home, having friends that are girls, and wanted to be with him any time he hung out with his guy friends. Whatever they broke up before she gave birth but tried to be civil and coparent for a year. He slept in the living room and gave her his bedroom out of the place they were staying with his mom and sister. She talked to other guys and he talked to other girls but they were broken up! So when she found out he was moving on, she tried to come at him with a knife and slash his tires. Anyways fight breaks out and she calls her dad from NY who then calls the cops and made a scene. My husbands mom says that’s enough and books her flight to NY. The bitch ofcourse takes their daughter and one the dudes she was talking to, get an apartment together and now have an expensive lease of 3 people in a shitty ass apartment in a shitty ass neighborhood in NY. I been there already and she talks so high and mighty like she got everything on her own and been out on her own since she was “16” and no ones ever helped her. Mind you my husband and his family sends her money, clothes, toys and things for his daughter. On top of that she didn’t even get with the guy she roomed with. She found another bum who does drugs and threaten to snatch her daughter from school and commit suicide cause of her. She still keeps that dude around til this day and talks mad shit about him to my husband whenever they on the phone. My husband was younger back then and more careless and he admits he didn’t try as hard to get his daughter back. He did have his daughter at times in FL and went to NY to be with her. Til this day he doesn’t wanna deal with courts having an order on who gets their daughter and when they do. Last time they went to court, she tried to get him for more money then he was already giving($300 a month) to the judge ordering it $25 a month 😂 like that’s what you get for being greedy bitch. It’s her fault for moving to NY from FL and now is stuck having her daughter’s parents so far apart. Honestly our 2bedroom apartment is WAYYY cheaper and ALOT nicer than her crappy 3bedroom. We’ve had his daughter now for a month and she’s already bitching at my husband to have her back and we don’t take care of her blah blah. Mind you, I have a son who they play great together with, she has her own bed here in a shared room with my son(over there she sleeps in the same room as her mom on a cotton pad), I work from home so I always play or have an eye on them, there’s nicer parks here and more space in our apartment than hers. She likes to boast she works 2 jobs and pays for her daughters school, has a house all by herself, has her own car(she barely got like 3 months ago). I mean she wants a fucking cookie for being a single mom. I been a single mom for 5 years until my husband came around and my baby daddy literally lived 20 mins away yet he never made the effort to see his son or be in his life. I’ve had my own car 3 different ones since 20, lived on my own since 22(we are 27 now my husband and I) but you don’t see me begging for an award or having my baby dad in his sons life. This bitch hates me and swears I manipulate my husband and didn’t let him see his daughter. Like what? I’m been around when he tries to FaceTime or call and she will either block him, not answer, cuss him out and say how he’s a shit father. He is trying to make up for the past but she keeps bringing it up! Ohh! And now I’m over 10 weeks pregnant so guess we both his baby mom now. The part that made me cringe is how she said “we have a kid I’m in your life forever so we gotta deal with each others bullshit” 🤮 like no he does not. He can take you to court and not have to. But that’s gonna be for another story. Just wanted to vent so if you read all this… THANK YOU! You a real one. I dislike this stick figure looking bitch. Ain’t no one insecure but her damn self not letting go. She thinks she can live her happy life and my husband can’t have his own and his daughter at the same time. And yes my husband has receipts, I’ve seen proof myself with his mom and sister but his baby mom will deny any of that til the day she dies🙄

Oh! And yes we have all sat down and tried to talk like adults. She hates when you call her out on her bullshit and she will just freeze up like she don’t remember. Fast forward, we thought we were on better terms but she is like a bitch on her period 24/7 having mood swings and going back to her shitty attitude 😒
