The love you have for your father, mother, siblings, and friends is different from the love you will have for your soul mate. The feeling is incomparable to any other.
There are a lot of ways to express love. The primary purpose of manifesting love is to make the other person feel special and make them feel that they matter to you.
You can do this easily by sending them a greeting every morning and night. If they had a bad day or are sick, you can send them a cute love SMS photo. The smile that will come on their face is the most beautiful thing you will get to see.
