SOULMATE... To be honest, I don't believe in a soulmate. (^_^)
In a relationship boyfriend, girlfriend, and couple. Once you have a mutual understanding, you are inside of what they call RESPONSIBILITY.
In responsibility, you need to be honest and sincere. You choose that, and not someone else. So God puts the brain on the head to think before you do what you want to do if it is right or wrong.
Well, sometimes intelligence brings pride to man. So they must learn to be humble...
Yes, that is true! Those are the main ingredients for a successful relationship.
For my part, I actually believe in "soulmates" as just a concept. It could be true for some, and untrue for others. However, I also think that the concept of "soulmates" do not apply in romantic couples only. The same kind of strong, indescribable bond can also be found within friends, and family as well. :)
