Sometimes when a rat already has his permanent residency and feels he’s in the clear, he may seek out girls for the purpose of using them to help bring people he knows back home over to his new country of residence. I don’t mean paying a girl to do this either. I mean by seducing her, telling her he loves her, playing the same mind games rats play, making promises that if you do this for him, he will marry you after his friend/brother’s residence is secured and the divorce takes place. They aren’t always looking for money and a visa for themselves. If you start getting friend requests and messages from people he knows, it could mean he has given them your information. Also be aware if he has posted you all over his Facebook. This should be normal behavior to post your significant other but they do it to make their friends back home jealous or even to advertise you to them. You won’t notice this because it appears he’s so into you by posting lots of pictures and sweet status updates but overtime you’ll feel like nothing but a trophy when your relationship isn’t as good as it appears online. They likely have other accounts where you are nonexistent. In extreme cases, they may blackmail you into doing what they want especially if they have nude photos and videos or other compromising information on you. They will often study your profile and learn who your friends and family are so they know who to send those nude photos to. He may also start adding your female friends from fb as well. I haven’t seen anyone address this issue so I hope it helps!
