Few hours after leaving aftee ww talked (after she slapped my head sideways) my married fb’s wife shows back up on my doorstep. She tells me aftwr she left and went home after we talked, her plan was to try to figure out how to talk to her husband about if me being his side piece was something he really needed then they would figure something out because she wanted to be with him. That alone was a bit of a wtf because after he had ignored me for a week and then blindsided her and me both by confessing to her that he was seeing me for a f*** or an occasional b*******, I certainly had not signed up for that regardless of how great he is at s**, we had not even discussed it when she was here. She had a packed bag on her shoulder and was angry and had been crying. She shows me a pic on her phone that is a guy she saw leaving their home just before she pulled up. When she walked in her husband was still naked and getting rid of the condom. She said they barely spoke as she packed a bag and told him she was leaving. I mean not to sound guiltless I was being a willing mouth and a** to her husband but this was a thing on any scale. She sits down and word vomits/rants and I let her before I spoke. I told her to park the emotions for a moment and pointed out that even though it had been months since he had touched her that I had naively believed I was the only guy he was doing this with and now neither of us could be sure or trust he was clean. That had not even occurred to her yet. I told her that we were both going to be tested in case this was an even bigger problem than either of us realized. She started crying again and said she had not even thought through wherr she was going to stay. And because despite my together sane stable way of living my life I did not even stop to think what a stupid thought it was I just blurted out she could park at my home till she had time to breathe. She was immediately grateful and I was faking a no problem attitude because hey I was at least part of the reason she was in this boat. We just got back from the testing and I made her and me a drink and told her to just clear her head and ordered food. She is currently crashed in my spare bedroom while I pointlessly ask myself how in the f*** I managed to set myself up for any of this, as if me letting a married friend f*** me behind his wife’s back and then offering her a roof over her head was not entirely self inflicted insanity. And literally while I was typing this to post here, he texted me saying he had a feeling he was gonna need a place to stay for a few days and I told him that he may as well stay home until he hears from her because she was already crashed out in my spare bedroom for the present. His next text was simply “oh f***”. I texted back and agreed and said I did not see any point in talking again and that if she or I got bad test news we would do him the courtesy of telling him. He actually got s***** about that and I told him he had no right to be. He tried to deflect with some crap about she had always still had a thing for me anyway and I responded with LOLOL. Told him he needed to talk to her not me. So have managed to f*** up my own and another person’s life while realizing I prob just lost out on the best s** I have ever had. And now I am a bit concerned about what he said about her still having a thing for me more than I am the low likelihood of bad news on the test results.
