I worry about this. But I wonder, if you're aware of it, can you prevent it? I mean, if you work on your marriage and stay connected then the itch won't happen...I guess?
I have never experienced the 7 year itch, but I have experienced the 3 month mark after a breakup.
No doubt those turds would call to "see how you're doin" almost 3 months to the DAY of a break up.
