You've got a good question. I'll try to answer you.
My wife didn't do that, but she did state last October that she was unhappy and wanted a divorce. We agreed that I would go to counseling ASAP. I did. Was put on Lexapro and begin seeing a counselor weekly. I was very depressed at the time and we worked on that first. Then we did couple's counseling. My wife said on several occasions that things were going well. She also said that "there was nothing I could say in counseling that would cause her to leave me." The end of March/first of April something happened in counseling. Something I said that caused her to "realize" that there was nothing I could do. She said that she had really already made up her mind last October. (I don't know that she's being truthful about this.) Also, the first week in January in went to my MD for him to test my testosterone and a regular physical. He said it was in the "normal" range. He prescribed Wellbutrin for me also. After we separated in April I had another appointment with my MD and questioned him in detail about the testosterone level. He said that it was 340. The normal scale is 300 to 1000. So I was on the low side. He prescribed AndroGEL (testosterone gel).
I would like to think that when I realized just how unhappy she was that I did take action. I really was trying in counseling. I wish now that our counselor had focused more on the sex issue.
Ok, I may not have answered your exact question. I don't think she would do exactly what you've described, but if she did I would probably be angry at first, but would quickly do whatever I could to be the one at the bar for her every night. But, I am answering your question after reading the SSM book and having the "benefit" of these past 7-8 weeks. I don't guess I really didn't understood the problem fully until I read the SSM book.
One other thing... since my wife left she is still wearing her wedding ring and says that she is not seeing anyone or having sex with any one. All evidence also shows that she's not seeing anyone. So if sex was her only drive she would have found someone by now and/or she would be pushing to finalize everything with the divorce so she could freely see someone.
Please let me know if I haven't answered your question.
