Transfer Steam Library to Dbd?

So I still have his Steam Family Charing on my current laptop (my ex's laptop) and at Dead By Daylight all DLCs he has ever bought with it were transferred to me. But he wants his laptop back soon and I'll get my own PC and when I log back on to Steam, but without his Family Charing I still have the Dead By Daylight DLCs? Because I've already leveled characters there, I somehow can't imagine that this is simply a mess of the game, because then, for example, talents are simply gone etc. So how is that then?

As soon as he turns family sharing off, that's it

I don't see why you should leave the possibility open for your ex to let your steam play when you are no longer in contact

The DLCs are tied to the corresponding account. New account equals a fresh start.

At the latest when you are playing the dbd and he also wants to play, he will kick you out and you can't play until he goes off

I doubt he'll put up with that

You didn't quite get that haha. I have Dbd myself, so I don't have that through his Family Charing. But a couple of the DLCs were also transferred to me because he bought them on Steam. So say We have these figures with us and I with me

Yes, but I have my own account. So I have my own dbd and he has these DLCs and I have them too. But my dbd is really mine too. We only bought the DLCs, but they were also transferred from me, so we both have these characters and can play them at the same time

When he turns family sharing on, they're gone

Then you can no longer use the corresponding DLC characters. But you keep levels, cosmetics, etc. They are not lost and are only "frozen". If you buy the DLCs again, you will have access to the characters again.

Ok, but how is that supposed to work? As I said, I've already leveled the characters and played a lot and that's all randomly gone?

Ah ok thanks
