A few days ago, my wife told me that she heard from her sister-- she's getting married. IIRC, she's only been dating this guy for like 6-8 months. She's also pregnant.
And then they started fighting. Why? Her sister flat-out said that she didn't want me going to the wedding.

What have I done? Well...absolutely nothing.
Literally. Last time I saw my sister-in-law, I got in her car with my wife and a friend and she immediately started screaming at me, demanding that my wife and I have a baby, time is running out, etc. Then "DIVORCE. HURRY UP AND DIVORCE" over and over again. Not even a hello.

So she's been upset that we haven't had a baby and then went and got herself knocked up. I suspect that she then demanded the poor guy marry her after that. My sister-in-law would be a perfect yakuza enforcer with her violent attitude (I have witnessed her go to her parents' hours, demanding money, and wreck shit until she got it) and I really, really feel for the fiance...who I never met. When we went to Japan a few months ago, she wouldn't introduce us.
My wife has been acting like a champ and was pretty much just like
"bitch, I ain't going anywhere without my man" right back. Am very glad we don't live in the same country because her sister would be kicking down our door if we were anywhere close by. I suspect she needs speak with a doctor and possibly be diagnosed for a condition, but it will probably never happen.
