It takes two to tango
That’s how you maintain good relationship
our feelings falter when we are weary
I don’t have energy for anyone when I’m weary
I become dependent on anyone who shows me the slightest concern
That is how a girl feels
That's how when someone we love leave her
So, don't worry when a girl cares about you so much so it irritates you. Starts to worry when she doesn't care any more.
Have faith in love. Try to understand your partner. Read about them physically and psychologically. InsyaAllah you will get along well together.
