Here’s the sitch:
After a lengthy period of singlehood and loneliness, you meet a person of the gender appropriate for your sexual identity and preference. The two of you hit it off wonderfully, compatible in sex drive, politics, religious philosophy, and whatever else matters to you.
Two months into the relationship, you broach the subject of future commitment. You’re not proposing marriage or cohabitation, but you want things to head that way, and so you want to agree to be exclusive. Your lover sighs and tells you one of the following:
(a) Five years before the two of you met, your lover’s child was kidnapped and murdered. The killer got off on a technicality, but there was no doubt of his guilt, and so your lover snapped in rage and killed him. At trial, he/she was found not-guilty, either on a temporary insanity plea or outright jury nullification. (The lover provides documentation–news stories, et cetera–to back up his/her version of events.)
(b) The same thing happened ten years before, except that your lover was found guilty and served a stretch in prison. Similar documentation.
© Same as (b), except that the killing not only premeditated but also was so shrewdly planned and executed so that your lover was never arrested or even seriously suspected of any wrongdoing; it looked like an accident. No documentation, for obvious reasons.
(d) Same as © except that your lover was a suspect and has been on a fugitive using an assumed name for all this time. No documentation, and your lover does not volunteer his/her real name but agrees to tell you if you ask.
What do you do?
