No, Inter is still want to keep Lukaku, but they just want don't want to spend huge money to sign him. It's all depend on Lukaku decision whether he want to join Inter or Juventus, Juventus have offer better monthly salary and higher bid for Chelsea. I think the reason is Juventus don't have any other good striker except Vlahovic, so Lukaku can be a substitute player. There's a rumor where Vlahovic will join PSG or Arsenal, so that's why they're looking for a new striker.
Football is one sport that has a lot of uncertainties. Inter really wanted to get him but with the way it is now, I think Inter have angrily pulled out of talks to sign him permanently after learning Chelsea were in negotiations with Juventus. Despite Lukaku's pledge of loyalty and his success with Inter Milan, Lukaku has agreed personal terms with Juventus. Lukaku wants the move and it does look like the deal will materialize.
Lukaku looks well settled at Inter Milan, he's doing well for the club so I don't know why he really wants to leave if Inter Milan is able to meet Chelsea's demand. Except he has a 'thing' for not staying in a particular club after 3 years because that's what it looks like going through his club history. The latest UEFA sanction on Juventus, saw them dropped from a fourth place to a seventh place finish, thus they won't be in the champions league and europa league next season, which is more reason for him not to favour the move. Inter Milan really wants him to stay because of the departure of Edin Dzeko to Fenerbache.
