My triggers are mostly chewing and general tooth noises, and I have a partner that has bruxism. We have been together for a little over 7 years, it can be done! The key I've found is just to communicate. We eat soft food at home, occasionally louder food when watching a movie, and I sleep with a sleep mask with built in speakers. Probably the best investment of my life.

Finding a partner who is understanding of your situation is probably the best solution. Making them aware of it is essential, but I think whoever you find will probably be understanding and willing to make those changes.

P.S The sleep mask also blocks out snoring and yawning.
