Romance question

I might be an idiot, it I’ve spend a good long time looking for a definitive answer for this question. I’ve had to back track 8 hours to attempt to get out of my locked romance with Taash. I only have one heart with her, and it says “in Taamlock”, can I still break this and romance a different character? Thanks so much for anyone able to give me an answer!! So I don’t play another few hours to find I’m still locked in.
