1. Actions are more important than words. A person who really experiences strong feelings confirms them with actions. Care manifests itself in small things: attention, readiness to help, respect for desires and borders. If the words remain only in words, you should think.

2. The sequence of behavior. Real emotions do not disappear after quarrels or difficulties. If attention and heat manifest only at convenient moments, it is rather a game than sincerity. Feelings are manifested stably and are not dependent on mood.

3. The willingness to invest. Sincere interest always implies participation - time, effort, support. If a person is limited to promises, but does not take specific steps, this is a signal that a void may be hidden behind words.

4. Honesty and openness. Anyone who is really interested will not get away from conversations, hide the details or get confused in his own words. Sincere feelings are accompanied by honesty and transparency.

5. Emotional involvement. Real emotions are manifested in how a person reacts to the joy and difficulties of another. If there is empathy and sincere joy for success, this is an indicator of the authenticity of feelings.

6. Time puts everything in place. Beautiful words can deceive, but over time it becomes clear who really appreciates and who plays. Real feelings withstand the test of time, the promises are easily dispersed.

The main rule is simple: do not rush to believe the words, but to observe the actions and how much they coincide with the promises. Sincere feelings are always visible in actions, care and stability, while empty words remain only sounds.
