Regarding the other options:
- A private investigator is far too expensive for either one of us to afford.
- He clears EVERYthing on his phone right down to the PHONE numbers. The phone is totally empty, there's not a trace of anything on it.
- His laptop has a password on, which despite repeated attempts, we don't know. He'll always make sure he's alone or WELL away from anyone when typing any passwords in. My sister tried 'popping' up, or sending him downstairs for something so he'd have to leave his laptop unattended but he 100% always 'locks' it so no one can get in. He doesn't even have a guest account anymore, it's only his one account. His charger broke and while he was waiting for a new one, he's taken to going to internet cafes!!! And even though he's got his new charger now, he still regularly goes to internet cafes and only uses his laptop for movies now!! So we can't even see what he's doing and are even more in the dark about the situation.
- My sister can't just leave him. Unfortunately, our society doesn't work like that. It isn't her choice. There's this saying in our community that when you get married, you don't marry your partner. You marry his entire family. And it's true. There is no "freedom" at all. She's desperate to get out of this, especially as it's making her health deteriorate, she's constantly stressed and ill. The more she tries to make it work, the more it backfires. As soon as she backs off, everyone starts pointing fingers at HER and saying it's her fault for not trying. Whether she's holding on or letting go, it doesn't make a blind bit of difference to him. They've had a "break" from each other, that didn't do anything.
- There are a lot more indications regarding his sexuality. Twice she's woken up when he's been on the phone in the middle of the night, and he hasn't switched the phone off fast enough and she said she definitely heard a man's voice on the other end of the phone, but more than that, he was actually flirting on the phone with him! There are a few other "intimate" things that I'd rather not disclose but they definitely point towards him being gay. He has a female cousin who absolutely hates my sister, and this cousin is very close with my sister's husband. Apparently growing up, they practically lived together for almost 10 years. Anyway, one of the first times she met my sister after the wedding, she said to my sister when they were alone "I'm surprised that he married a woman" and walked off. Now, that's definitely a VERY weird thing to say and we'd try and get more info out of her if it wasn't for the fact that she absolutely hates my sister for no apparent reason. It's been 2 years and my sister REALLY tries hard with her, but this cousin has made it perfectly clear to my sister that she doesn't want anything to do with her. She actually spat at her feet once, so that's another dead end.
