My friend has a crush on his step mom. Her and his dad got a divorce a couple years ago after being married 8 years. They had a son together who's 9. He wants to know if it's wrong to date her ? She's 26 he's 25.
The fact that the father and ex-step mom are divorced makes no difference - the emotional dynamics of the past relationship will affect the present one. It will most likely erupt into anger, recriminations, misery and yet another failed relationship.
I wouldn't be surprised if it destroys his relationship with his father.
OK, I did the math and I think you're asking the wrong questions. So, did your friend and his step-mom help each other with their homework when they were in high school? How did that work? What was it like sitting next to his step-mom in class? I think that would be kind of weird.
