A relationship always needs to start by an interaction between two people. That relationship will be developed and maintained by the respect and faith for each other. If there is no interaction, communication, there will be no relationship has been made. Even for the existing relationship, if you two are not sharing together, your relationship is going to fade away.
Anyone needs to be respected, especially in love. Because respecting each other is one way to show that you love your partner. If you love someone, but you don’t respect him/her, that feeling you think it’s love but it isn’t.
Especially, love needs to have absolute belief from two sides. You have to trust what they say and do and of course trust the love they give you, as well as trust your self, trust the love you give them. If not, there will be no good reason to maintain that relationship.
