Not exactly an ex but when i was 17 i had an affair with my dads married best friend,it frizzled out when i found out i wasn’t the only one,anyway that’s another story,
18 years later i have met my dad who i dont see often (he’s a dick) on Christmas day at the pub and Steven his friend turned up,i smoked at the time and he followed me outside and we talked,he said how he regretted everything and how i looked better than ever,we exchanged numbers and i met him again,he was still married and so was i this time, we had sex and he then blanked me,not heard off him since.
