Trust is difficult in building any type of relationship whether it be romance, friendship, or business partnerships. It is a two way street. Both individuals or parties have to have confidence in each others intentions, what they have to offer one another. Someone who has been lied to and cheated will most likely have trust issues. There will have to be some type of reassurance from both people to ensure some type of trust. The best way to start any honest relationship is with trust. Sorry, there is no other way it can happen.
