Trust is a huge part of any relationship, whether that be between family members, friends, or partners. Essentially, I think it is the foundation of any relationship. However, trust is a hard thing anymore. I think more and more people have a tendency to lie now a days, which is sad. Social media does not help because everything has a password or passcode anymore. Yet, I think anyone can work on it. Taking baby steps helps. Admitting your wrongs and seeing the strengths in one another is a good step. Often times, we have trust issues because of our own insecurities too. Communication is key. I think trust can be rebuilt even once it has been broken, so I think you can work through this if you both put in the effort.
