Where there is no trust, there is no life, where there is no trust, there is only suffocation, where there is no trust there is no joy, where there is no trust one can only exist, not live, where there is no trust there can never be love. Where there is no trust happiness cannot exist, it is impossible.
It’s all-consuming. If you can’t trust without reason, fix yourself, if you can’t trust & there is a good reason, leave. Living that life of mistrust prevents noting from happening except perhaps the joys in life that will be missed.
If someone makes a misstep you have two choices, forgive and let it go or not forgive, if you can’t let it go you are now down to one choice, you have to leave so the both of you can get on with your lives.
