A relationship without trust is much more like a car without gas. This is a metaphor that simply depicts that if you do not have trust and faith in your relationship, it is simply not worth your time and emotions.
Trust is one of the major components that you should be having in each and every relationship, be it that of a mother and a child, a parent and a kid, a teacher and a student, a husband and a wife, or even among the friends.
If you do not have that trust factor in your relationship, you are just faking it around and that does make absolutely no sense.
You must be able to understand that if you do not have trust in the relationship, it is more like that car without gas that you cannot ride anywhere!
If you do not have that trust in your relationship, you can spend as many months and years as you want to in staying within it but it is not going to have any destination.
This is pretty similar to that of a car that is not having any gas within it so you can stay in that car as long as you want but you can never expect it to take you to another place.
It is important to understand that when you are investing your time and emotions into something, it is quite obvious that you will be expecting some return out of it, and that’s when you should be having the trust component to make things work!
