Every relationship has purpose and benefits, either good or bad.
You must be able to discern and discover the purpose of every relationship you are into.
Relationship with friends, fiance or fiancee etc.
You must be able to know the merit and dismerit of every relationship you are into to avoid unnecessary heartbreak, disappointment and problems.
Don't be too quick to tell people about yourself on a first meeting,know thier purpose of coming into your life, discover the kind of person they are.
