If there is no trust in a relationship, there will be no respect and no harmony.
You should never enter into a relationship if you feel like you don’t trust him one hundred percent because if you don’t, it means there are some things that he should work on in order to win your trust in full.
Especially if you know that he wears the label of being a cheater in past relationships, you shouldn’t think twice about taking some time before you start trusting him with all of your body and soul.
You want to make sure that you will not have to overthink everything and fight over stupid things just because you suspect his words and actions.
