Not a skid issue, it's his sister...AGAIN
My guy and I have been together for about 3 yrs. We have crazy love for one another, we fight rarely (we want to get married). Our problem more lately is his slightly older sister (40+). She's always asking how we are, and she's always digging for details. She calls/texts him a minimum of 5-6 times a day (she's nuts). She calls for nothing other than to chat and to gossip about their other siblings, which all but one stills talk to her (similar reasons). I've been separated from my "husband" for 6-7 yrs and we've finally come to a point we can finally divorce (house/money/his resentment issues). His sister, without him knowing, called our county office to see if I had filed yet. Obviously they said no, because in our state we can file any where, our county happens to cost the most so I decide to file in another county to save a bunch of money. She decided to pretty tell him I'm lying about everything (she met me ONCE) and he said to her to F off. Crazy sister, of course, calls the mother to explain her investigative reporting. Mom brushes it off, knowing the fuller story.
I can't take this bitch anymore. Many (many!) times I've considered leaving due to her. She's fat and lazy and says she can't work because 4 of her 5 kids are in school. Since she was checking up on me, I checked up on her and found she was 50k in debt, and actions were being taking against her, something she wanted to clearly hide 
My hunny brought this to the attention to the other siblings she's slammed for not paying bills. Not surprising, she doesn't want to talk about that.
What to do? Confront her myself? (Huns said she should confront me herself, but she never has)or just let it lie? Keep in mind, we'll probably be married soon 
There is no reason at all for
There is no reason at all for your fiance to have anything to do with his sister if she behaves badly. She is not his ex, has no call on him, I suggest he just ignores her texts and lets her calls go to voice mail. As the previous post points out, if he does anything else he is just enabling her and rewarding her behaviour.
I've told him all along, stop
I've told him all along, stop taking her calls and answering her texts (it feeds her nasty behavior). This fighting (for many different reasons) is a sad replay all the time. She starts a fight, they don't talk, eventually she calls and plays all nice. Almost immediately she starts her crap. BF doesn't talk to her for a while. She complains to their mother that her brother is ignoring her, and eventually to appease his mom he starts talking to her again. Since this drama he has stopped talking to her. But I'm certain it's just a matter of time before mom makes him feel guilty, again! It even came to a point that a few months ago I bought a muscle car (I like fast cars) and she commented it was inappropriate of me to buy it. Ummmmm, HELLO?!! I'm a working adult w/o kids. I'll buy whatever I want, it's my money!
She FB friended me a couple of years ago, which I accepted, only for her to ask BF why I posted a pic of my dog or why I like chicken salads (really!). Bitch went psycho so I defriended her. I've NEVER had this problem before.
