maybe some one who has been through this "phase" can shed some light?
in my case it was the powerful sense of rejection i felt. i wanted out for a lot of the duration of the relationship, too. that powerful feeling of rejection, at the time, i would have done anything to reverse it. i fantasized about the ways in which i could, and ways that would put me in control, an awful lot.
Why on earth do I want her back? Why am I willing to trade my sanity for companionship?
i read through your posts, and i realize you arrived in a crisis state so it stands to reason, but i dont hear much if any mention apart from the sex (is that part of it?) that you liked about her, so its hard to say in your case.
its possible, though, that its as simple as the fact that grief and letting go are uncomfortable for anyone, excruciating. it got a lot easier for me when i stopped trying to fight those feelings (ie i thought something was wrong with me for missing her and wanting her back) and simply acknowledged them... .then they got a lot easier to tend to, and work with.
what do you think?
