The best advice is to show love in the acts
avoid the following if you want true love:
1. Avoid selfishness.
2. Be loyal to the one who you love.
3. love and respect the parents of the one you love.
4. Be a good thinker by finding excuses if the one you love made mistakes or broke a promise un intentionally.
5. Respect the one you love.
6. Share the feeling if he/she are having a bad day.
7. Share some of the responsibilities like school or rental payment.
8. Go for a special dinner or lunch once per month with the one you love.
9. Ask the one you love which things he/she does not like.

11. Avoid cheating on the one you love, because if you cheat then you will also be cheated by the one you love, or your cheat will be discovered.
