Input: Text: met a guy a couple of months ago, we got involved and it was fantastic. the sex was perfect, and for someone like me, that's a rare thing. he was only in town for a few months, but at his insistence, we continued to be involved long-distance. 

some time after entering this phase of our relationship, i get a phone call from someone asking strange questions, saying he'd referred her to me as a potential roommate. i wasn't looking for a roommate, and i didn't give her any information regarding the nature of our relationship, because we were never official, and i didn't know who it was or why they were asking. after ending the call with an intent to call her back, i asked him if he'd given out my number. he told me no, and that it was "his *wife* freaking out."! for some reason, he assumed i would lie for him, even though he had told me they were long separated, and that the only reason the paperwork hadn't been finalized was because of his work schedule (he travels a lot...)

turns out, they were happily married and this woman had no idea that her husband had been sleeping with other women whenever he was away, much less continuing the relationship after returning. i still don't understand why he didn't just let things end when he left, like i wanted. 

it took me about a day to wrap my head around the situation, and determine the right thing to do. in that time he begged me not to say anything, and to please just let him "handle it" (of course). told me how scared he was, how important she was to him, that his career would be in jeopardy too but that all he cared about was not losing her. 

i know it seems obvious the right thing to do, but stepping in and wrecking a marriage when you were just someone on the periphery can feel so wrong somehow. i didn't feel it was my place at all, but she had sought me out, and i couldn't deal with having obscured the reality of the situation to protect him when he was doing her such a wrong. 

i really liked this guy, he was always sweet to me, respectful, and considerate. it's hard to explain, but we had a kind of...bond, and i can't help but feeling like i betrayed him. i texted her, inviting her to call me back when she was alone. she did. i confessed. most awkward conversation of my life. "did you have sex with my husband?" never have i wished the earth would open up and swallow me more than i did at that moment. but i told her the truth.

she wound up texting me later, saying he was denying everything and that i was "crazy" and it "never happened", so she asked for proof. i had to go through our messages, pictures he'd sent me...after i thought the situation couldn't get any more painful. i didn't want to send them, didn't want to look at them or be reminded of or share those intimate moments, didn't want to be involved any more...but i know too well that feeling of not knowing what to believe, and wanted her to know what was real. 

i just can't explain the feeling like i was deeply betraying someone, but it still won't go away. when all was said and done, he just said "why? why did you do this? please just tell me why"

my heart is broken in all kinds of places. if there's a lesson to be taken away from all this, it's this: to be "separated" (which, as it turns out, they were not) is not enough, papers need to be signed and at city hall before proceeding. never again.
