Love and attachment are 2 different things
I learned that the feelings I develop for people is natural and positive because my intentions are good. That's what love is, when you feel good energies from another person and all your intentions are good. Don't feel ashamed of that feeling.
But don't grow attached too quickly to a person until you know them and that the feeling is mutual. Other people aren't objects that you can control or make them belong to you. It is selfish to wish to possess another person based on how you feel about them. They have their own minds and feelings. They feel just like you. Love isn't attachment or possessing another person. It's your good intentions and good feelings they filll you with but you should not try to become self absorbed and try to keep it for yourself.
Learn to separate loving a person and possessing a person. It's like a rose. Would you take a beautiful rose from it's bed just so you could have it? Or would you let it stay rooted so Every body else can enjoy it too?
Love also can be onesided and that is also okay. Love isn't something you give or take away because your feelings are hurt. If I ever loved you, I'll always love you because love is something meant to be shared even with people who don't know how to accept it
