This character is romantically impregnated with another; that is to say that whatever his situation is, he will be forever in love with this person to such a point that if he doesn't build his life with this person or they separate after a life together, he will remain voluntarily single all his life "prisoner" of his passionate love towards the other.

Sorry for all these examples but it's so that you can better understand this trait of personality (in case where I would have bad defined it).

Denied. I understand what you mean (though admittedly it's a weird way to say "sexual/romantic obsession", at first I thought this was a counter-trait for Forced Pregnancy), but I still don't see the point. This is really up for personal opinion with some quite vague criteria.
