Early in our relationship, my wife sent me out to the storage shed to look for something. I came across her journals and not knowing what they were, read them. I can verify she has been with about 30 other men and think the number may be as high as 40 or so. I freaked out. Ended up in a mental hospital over it. I have been to bed with exactly seven women. While many of hers were one night stands, there were a significant number or men she stayed with for anywhere from three weeks to three years. This includes two other marriages.
The other thing which caused me dispair for a long time was she went through her change of life about two weeks after we got married and her desire for sex stopped cold turkey. Instead of every other day, it is now maybe six times a year.
So, I have had to work through these issues. Here is what I have concluded;
1. I am lucky she did not catch a nice little social disease and pass it to me. She may have been easy, but she was and is picky on who gets in her.
2. Why does it matter who she has slept with. Obviously it did not work out. Flip the thing around, would you listen to someone who poked their nose in your business? Why would it matter how many you have been with? So you have had three and she has had 14. She has been open to try new things, you thought the first girl to sleep with you was the one you kept forever. Did not work for either of you and now you have found each other....work on THAT ONE relationship and let go of your past ones and hers also, they simply do not matter other than they have made you the people you are now.
3. She has chosed to stay with me. I am more important than they were/are. If I were not, she would not be with me.
Now let all that BS go and if you still find yourself thinking about it, it may be because (like me) you are in reality mad at her and jealous she has had more fun than you have. Fun is relative, make your most fun today.
