It is personal, but not too personal. This was a very painful period both for Carol and for me.
I don't have time now to write a full reply. But the answer is "yes and no." We split up for several reasons, but you can say that the reasons were rooted (at least in part) in the age difference. For example, Carol became extremely bossy. (I hate being "bossed.") This may be a danger in any relationship where there is a substantial age difference--the older person may try to boss and dominate the younger person. Carol became extremely, insanely jealous of me (without real cause), and this may be a danger in any relationship where there is a substantial age difference. Third, Carol and I had a big fight about a movie we saw, What's Love Got to Do with It? Now, we had discussed going to see Sleepless in Seattle. With Carol's habits, we were running late, so I dropped her off at the door to the theater, put some money in her hand, and asked her to buy the tickets while I parked the car. So she bought tickets to a movie I barely mentioned in our discussion, not the one we had agreed on. When we left the theater, Carol was crying and seething with wrath, why had I forced her to see that horrible, sadistic movie? Didn't I know that her second husband beat her like Ike beat Tina? I made her relive those horrible experiences, etc. Was my ability to relate to Tina Turner, her music, her bravery in freeing herself from Ike's brutality, at least in part due to my age? (I've told this story in another post somewhere else on this board.)
There was much, much more involved. But generally all these negative forms of behavior and what I regarded as "craziness" emerged during the last year of our relationship.
Now, some people might say that all these things are just rationalizations I had seized upon to get rid of an older lover.
I don't think so, but then, this is my perspective.
