Mother-in-law Hell

and stole my bank statements …what I can do? My future Nasty Hong Kong mother in law just like what my professor said: if you are sure you will marry to a guy who has a HK mother, you have to prepare and get ready to suffer… I am on the right track now… My fiance saw my bank statement letters in her trash accidently and she said to him destroy that and don’t tell me…she stole my diamond ring and watches, plus super jealous I am being with my future husband, she want to know every single detail from us, what we are doing, move to where, what my family business is…..if we miss one of the point she will bad mouth me everywhere said to everyone I am the bitch stole her son then she started crying to the whole world: she lost her son this and that. The worst thing is she is using my fiance and my money, paying her home loan, because we are going to marry soon, he has to stop paying for that, and have to sell his share 40% of the house (and the home loan liability is under his name-his mother own 60% for free plus no mortgage liability …) when we want to start a new family together, she said she has no money to pay (of course she invest large amount of money to her investment plus she doesn’t want to withdraw her fix deposit $), we tried 3 years without her single cent payment of the house, but she want more and more, when we decided sell our share and move on, she said she want the whole house plus my fiance’s share, otherwise she can not pay for any cent of mortgage, my fiance just lost the job, that situation makes him go bankrupt, and by law without her sign we can not list the house on the market….what we can do guys? Depress!!!
