I wouldn't "count" them as read (completed), but I don't keep count of books read so it doesn't matter much.

If I'm discussing a book with someone I'm honest if I never finished it. I'll say, "Oh, yeah, I started that one and liked xyz about it but stopped because couldn't enjoy it any more after abc plot point (or, I put it aside a third of the way through to start another book I was more interested in, etc).

I bet reddit folks would be happy to help with guidance about choosing some books you might end up sticking with!
