Hi just wanted to share my opinion. @teddy i think what @Loratte try to say is that Ian didn't want any relationship for now with all stuff he has to deal with but Jo seems like he does so they are on different line. TJ clearly want Ian, no denying. Ian and TJ get each other becoz they knew each other long enough.
from what Ian said I don't think Ian still love TJ as in romantic way, he made it clear that it was in the past. but he does care about him, they r still friend after all and with 19 years of history it's hard to just ignore that. Why does Ian sleeping with TJ, they are basically FWB. From Ian point of view i think there is nothing for him to lose , they used to sleep tgt anyway + it will end when Ian goes far away(which what Ian has planned)
Ian sleeping with others is just a way of his life, well he has urge. I thought about it for a while but well it did not need to be with just TJ. Becoz 1.he's not in love with TJ in that way anymore
2. Ian want to have his own life apart from TJ, so It wouldn't make any sense if he still go for TJ.
he can do his own thing like @Loratte said becoz it's not like they are lover.
It's a bit confusing isn't it but im really looking forward to see more of Ian&TJ past along with Jo' s development
