A relationship without trust

A good relationship is with someone who I feel safe and cared for so I can enjoy myself. It is never about how a person looks, how much money they make, or any short term qualities. Once you break that trust, it’s very hard to regain, but if you truly love that person, should you do everything you can to regain it, or just walk away and give up? I care too much just to walk away. Trust is built with time and communication and letting go of what others have done in the past.
