Fantasy and sci-fi can get away with being door-stoppers, especially epic fantasy and sprawling space operas. However, 167k and no end in sight is well outside the norm for debut fantasy romance.
When I was starting out, the conventional wisdom was that agents weren’t interested in debuts more than 100k in most genres and 120k at the absolute most for fantasy or sci-fi. Even then, your odds were worse in that 100-120k stretch.
Now, those limits tend to be lower. I’m hearing 90k a lot, with 100k as a stretch. So if you’re shooting for traditional publication, this is almost certainly too big for one book.
Personally, I’d finish your book (a massive achievement in its own right) and then worry about all this later. Alpha and beta readers could help identify what works, what doesn’t, where it could be condensed, etc. and then developmental and line editors could help trim it down. Edits would probably need to be pretty ruthless to cut it down to a marketable word count, though.
If you’re after self-publication, word count is less of a concern, though at a certain point you’ll run into physical limitations when it comes to what can be bound in a single paperback or hardcover. Also worth noting large word counts are common to beginners and sometimes indicate bloat, so I’d still commit to detailed edits to be sure it’s in the best shape it can be.
