5. Less Conversations
Earlier, you could spend whole night chatting with her but now conversations going over ten minutes become heavy. You do not want to discuss the day with her and also you do not want to know about her.

6. No romance
The things you felt when you kissed each other are gone. The feelings of holding hands and those romantic hugs are not same anymore. The romance and spark of the relationship are finished.
