some of them are! mostly the bad temper and drinking habits, those are the two he's a little less shy about because people typically notice things like that easily. if you're cool with saying they met in college (he went to school in portland) then honestly this would be perfect, he did have a steady girlfriend for nearly a year there and was generally pretty confused about his sexuality at the time but if you wanted, your guy could have been the first guy he was serious with? if not that's cool of course! we can always say it was more recently after he left college too. whatever works best!
