Me and my girlfriend have been going on for a year, we are going to be engaged soon. My gf is 24, I am 27, we both have our career and dreams.The problem is, she have an elder sister (31yrs old, married with 3 kids), whom is always skeptical and also love to control everyone in the family. (My gf originate from a broken family with a useless father whom earn NOTHING n gave NOTHING to the family). The elder sister have been too controlling, and previously have provoked my gf's 2nd sister(22) and 3rd (26) sisters' relationship, ended up their bf broke off with them. Her reasons are alot, as if she's the legal matchmaker. And now, is our turn. She tries alot ways to break my relationship with my gf, we have even went to find her to talk, but she did not talk to me, but sent her husband instead, but funny is her husband is not interested to help her and "entertained" her by talking to me. We thought everything was done, but after sometime, she starts anoyying again when my gf bought a car n need to move to downtown to work, her elder sister now thinks Im bad guy that have "stole" her sister away from her home. But until now, she never did nor have the courage to call me to talk to me, but kept bugging my gf with alot of methods to get to my parents' phone number and wanna talk to my parents. I was like gosh, what is wrong with her, I absolutely dont want a person like her to talk to my pensioned parents. I worry she will talk rubbish and create alot misunderstanding between my pa...
