I've seen at least three IEI-ILE pairs together and then break up after a few years. The only IEI who would talk about it said that her ILE husband didn't believe in educating women. (She had a PhD in AstroPhysics, but she was working as a housewife.) The debate came up when it was time to send their daughter to college. Or not. The ILE thought it would be a waste of money to educate a woman. The IEI divorced the ILE and left with her daughter.
The IEI is now heading a tech company that is doing very well. Her daughter is in grad school. Lol.
Ah well, I don't think it's uncommon for narrow-minded people to associate sterotypes like that to entire genders. I've noticed my mother(SEE) would also try to emphasize the difference between Women and Men(along with Russia, her home country, and the US), and then impose her own personality onto those things. I'd also say that it's usually pretty comfortable for an ILE to take complete "intellectual control", and get frustrated when people who they don't see as equals(maybe because of sterotypes or that they have "bad reasoning") don't take their advice and command. Or maybe I say that as a D subtype, idk enough ILE's to confirm that.
My sample size was three couples, and I only debriefed one.
I typically find that ILEs are extremely liberal in their views. However, they might be unconsciously expecting a Caregiver SEI rather than a Victim IEI. The SEI will typically be a caring mother, while the IEI will typically take a more hands-off approach to her kids. At least, that's what I've seen. Again, from a very small sample size.
