Seperating the LI's would be way too early, but adding choices to reject them would be good in my opinionI think you can be confident about the Bella route.
I think we have a lot to look forward to in EP7. DPC will separate the LI's from EP7 and with all the cell phone functions he has reprogrammed, the players will be able to dive even deeper into the story.
I could imagine, after my research, that a battle of the LI's for the MC begins.
Not outright locking you out but i would like if DPC added choices, on my Bella/Sage save i already rejected every Jill advance and now i think MC is only friends with her and that's it. If people want to keep going for 2-3 LI's then sure that should be an option but i don't want to be locked on another one just because i made a choice in episode 2-3We're still in the very early days of this game, both in terms of the potential episode count and the in-game time, so I don't see any serious lines being drawn in the sand right now. Also, DPC might keep to the AL format of having a lot of cake and eating it too until near the end of the game, the difference with this game being that you can't get all lewd scenes in one go.
