Love & Jealousy ... Sometimes they are two highly interacting feelings & practically it's very often.
Now,what is Love? ... Loving can be two types physically & mentally but as here I am discussing about Love & Jealousy,I will discuss about the metal side only.
I think,it's the mental bond between two people about any kind of relationships.
Sometimes it's natural,sometimes u need to work on understanding relationships,ur resposibilities & urself about the other person ( not only about bf or gf,it's about anyone ).
& What is Jealousy? ... Jealousy is an emotion all of us experience at some point in our lives.Sometimes it's natural,sometimes u need to understand & control urself.
The Course of Miracles says there are only two emotions: love and fear.simply,It's been our experience that what's underneath jealousy is fear of one kind.
Now,about a men-women relationships ( bf-gf ) like other problems people can talk casually before giving much importance on the incident ( source of problem ).
Among all,always they should keep it in their mind that how much they love each other & want to trust each other.
So,I suggest Love & Trust the person u have chosen for ur life,try to control Jealousy & belive in staying togeather happily ur entire life.
