A woman that is reserved does not jump quickly into telling a guy she loves her. No matter how much she feels about him, she always try as much as she can to avoid appearing too cheap.
Guys in relationship with such ladies may feel she is not caring at all. She may hardly reply romantic messages and even when you call her and say ” I love you” she struggles to say “I love you too”. Guys do not think she doesn’t care, rather cherish her because she’s not too exposed to too much romance.
