Okay, correct me if Im wrong but it seems like you’re pointing a finger at the girl for him being homosexual??? How is that her fault? You’ve got to be kidding me.
Another thing, she was never told he was homosexual. She wouldnt marry him if he was, right? She lived with him for quite some time, experienced his distant behavior and was extremely disturbed by it. He kept it a secret from her for over 6 months before she started to suspect something was going on. Again, when you get married, the LAST thing you expect is for your spouse to be GAY.
The reason she was going back is because she was still trying to figure out what to do when she found out. She wanted to confront him and have it out but before she could, he pulled the plug on her. He knew he was caught and the only way out without publicly humiliating himself was to take the first step, divorce her and lay the blame on her shoulders.
