My sister and I are close. Always have been really, apart from the usual childhood sibling fighting.
She has teenage children from a previous marriage and they're good kids.
She married a Mexican man 5 years ago and he seems to really dislike us (all her family), is sexist and talks to my neices and nephews like sh*t really. They have tried incredibly hard and have been much more open and willing to accept their stepfather into their lives than I ever would've at their tender ages, and treat him with respect, but he gives nothing but rudeness and disrespect back to them. He has been most rude to me and now when I visit my DSis, he blanks me totally. All because I have told him in the past that he should respect my sister a little more. We basically say hello to each other, and then he will move to another room while I spend time at my Dsis' home.
My sister was recently ill with a virus-type bug and he still had her cooking his meals and never helped once with the housework, so while she should've been resting in bed, she was keeping on top of the house and making him his food. Her kids offered to cook for him so their mum could rest in bed, but he refused to take their offer.
So background bit over, my sister is a doormat, we all know that, all the family have tried to tell her he's such a horrible person but she is in love. She sides with him over her DC, and has fallen out with several family members over them telling her some home truths and suggesting he's a user.
So, the thing is that her DH's mother is now dying in Mexico. He is very close to her and lived with her until he moved to this country. He has little money because he sends the majority of his wages over to his large family in Mexico and they use it for living expenses and food.
As they have very little money and already have loads of debt, DSis has asked me to take out a bank loan for £500 to pay for a flight for her H to go home to see his sick mother. I refused politely, but when I visited her again yesterday she said for me to think about it, and was literally begging me to 'just take time to think about it', so i'm left in a very difficult place. Of course, I don't want to upset my sister. I feel so sad for the situation she is in, and since she got with him, looks so downtrodden and sad. So do I or don't I help her out?
