I agree larry
My bil (dh's brother) was sucked in, chewed up and spat out by his first wife.
He is vulnerable in many ways. He's a sucker for a sob story, and has all the common sense of a toddler. He has a long history of making stupid choices and getting burned, then suffering crashing depression.
Anyway, he picked up this horror online, and brought her over here from the States to marry her. An hour in her company and every alarm bell was clanging. She was quite clearly a total fantasist, and he just sat there with eyes like saucers lapping up every drop of bullshit as the gospel truth. The lies were incredible.
What with one thing and another she went back to the states, and he sent her money...lots and lots of money. He visited frequently but was not allowed to stay with his wife, as her parents did not approve of him. So he stayed in a hotel.
I could type for an hour about the sly, manipulative fabrications she pedalled out to keep the money coming in.
Eventually he was broke, and couldn't do any more. She divorced him.
Right at the beginning we tried to talk him out of the marriage, as we could see her exactly for what she was...she wasn't very good at hiding it.
He dug his heels in, and didn't speak to dh or I for three years...the duration of his relationship with her.
He has now (about 5 years later) f=got another one on the go...from Argentina. However, though she is clearly an oddball, so is he and they make a nice couple. He's not giving her any money, and she comes over to stay with him, and he visits her too. It all seems kosher.
He still describes his first wife as "the most compelling and intelligent woman I have ever met" though.
She was neither of those things...she was a monster.
There is no helping some people. Very frustrating when it's someone you care about. Don't make the mistake we did, and try to intervene. He will choose her.
Just sit tight and hope she fucking fucks off asap.
