Family Drama

Here we go again it seems... More drama with my brother and his crazy wife... What started this one out was that my mom wont co-sign for a loan for sil for 6,000.00... So she got all bent out of shape saying that my family doesnt want to help her yada yada... Lets start with the simple part, my brother and she have shitty credit so if they default on it my mom then has to be responsible for it and she is 68 and on a limited income... Then there is their track record in paying my mom back which most times was never and when they lived with my mom twice they freeloaded off of her and then when they moved out cleaned out food and other things so why the hell would my mom do it... I told her not to do it and stick to her guns cause she will get fucked in the end... Also why would mom take out a loan for sil when she and my brother fight all the time.. they have the crappiest marriage going and why they got married I will never know... And I told my brother not to have a baby with her but he did, but then there is still the chance the baby is not his, another long story... I dont feel sorry for my brother, he was warned before he got married and his friends kept asking him if he was sure... Everyone knew it was a mistake... I dont feel sorry for him cause he stays... You can give him all the advice in the world but then he will yes you to death and do what he wants in the end... I know he needs to learn from his mistakes but come on, enough is enough... And with all the fighting they do sil is constantly kicking him out... So again why would my mom take out a loan for them... And I am so sick of them using that mom took out a loan for me and has helped me in the past... She lent me the money to pay off a credit card and I paid it all back, she took out a loan so I could get a car and I paid that all back... And I pay back other stuff and when we can afford it we have given my mom money to just help her get by... What has my brother and sil done, squat... I really wish she would loose it in front of me so i can tell her were to stick it... Its so annoying to hear all this and never get to see it first hand and not be able to say anything to her... UGH....
