When I left yeshiva in Israel 20+ years ago, my thought was that I'll be back soon. Then I met this girl who had no desire and no interest. It didn't help that not only did she not do a gap year in seminary, but also several of her family members who went to EY from the FSU (where she was born) ultimately came to the US because they were unhappy in EY.
Now that I am older with older kids (who at the moment have no desire) the only likely way I make Aliyah is if one or more of them does it.
