My sister in laws driving me crazy!!!

Tabitha • My name is Tabitha I`m 25::Mama to my amazing son::Wife to my crazy husband:: Baby Number 2 due 7-18-2016 👩🏻👨🏼👦🏽❤️
I just have to vent so I'll apologize beforehand but omg me and my husband and my son(from a previous relationship) have recently moved 2 hrs away from our hometown this was planned for a while but shortly before this happened one of his sisters(he has 2) decided to mess up her life and run down here before we had a chance to even rent a uhual...me and her used to be very close but she was always against our relationship but we remained friends..she got on drugs and left her son and boyfriend of 8 years and went crazy(she was always and still is the one in the family who loves to pretend to be better at life than everyone) fast forward to now she has her son back after leaving him with us(which I did not like at all because we are were barely able to provide for ourselves) and she is living with their aunt 10 minutes away she has nothing because she ruined it all for herself after having a vehicle given to her she now has no transportation because of her bad choices and she just got a job recently and expects us to be her taxi and babysitter... I'm not against helping people but one don't tell me you need a ride and sitter u can ask at least and two help urself she is the biggest manipulater I have ever known she is always pushing herself into our life me and my husbands have had more than our fair share of problems that we have overcome and she knows this but feels the need to add to them and I'm just over it she is just on my last nerve I'm sick of seeing her everyday doing something for her every single day we can't ever have time for just OUR family it has to include everyone and what makes it worse is my husband sees no problem in this he acts like his nieces and nephew are his kids and he's so obligated to them buying them stuff I would never even buy my child for birthdays etc letting them do whatever they want but being so tough with the discipline on my son he puts his sisters before me I feel and it's driving me crazy I have told him over and over nicely but today I just let him have it maybe it's the pregnancy hormones but who lives this way he actually said when we moved in together after getting married how he missed being a kid and living with his mom and sisters and he missed how they did things(as opposed to my way I guess) I told him if he doesn't change he needs to live with one of them because this is stupid and that's out of line but this whole thing has been wayyyyyy too much the last few months I just went off...and my mother in law sees this and agrees with me she doesn't like her kids all being around each other bc she knows there relationship is so toxic and they want to bring him down if she sees it how does he not???! Uh I love them but I want to move so far away I can't take it end rant...
