How do I know when it's true love?

It's about destiny. One day it will come

when it lasts and lasts and lasts - true love grows deeper as time goes on

You can never really be sure. Love is a risk but what you can do is get to know each other first before committing to a relationship.

First of all I don't know your age.  Have you dated a lot ?  Finding just that right person that you want to spend the rest of your life with is difficult at best.  Do not be in a hurry.  If it is meant to be, you will know in time.  Refrain from sex for at least 6 months.  If he pushes you to have sex, that usually means that is the only thing he is looking for.  Most men ( at least the ones that I know ) stated that they waited for up to a year before having sex.  Just don't rush things, remember life is a journey.  Relax and enjoy.

As I told you once before, it is when the thought of asking this question never enters your mind.  In other words, you have no doubts, no second thoughts.  You know in your heart that you know.  If he feels the same, voila! and Eureka! You've found it!

It is different for everyone.  But when they feel the same way is a good clue.  And people change and during a marriage you can even feel in and out of love for one reason or another - hard times, loss, etc.  I have been married for 38 years to the same man and have never once cheated and I fully believe the same of him, it has not all been easy, but we have been willing to stick it out and there has not been one other person ever I would wanted to go through life with.  We have supported each other no matter what and have had each other's backs when necessary.

When you missing that person so much then you will know that it's true love.
