In regards to romantic relationships, Buddhism has very liberal views. Buddhism encourages independence through non attachment. Non attachment is the idea that in order to be fulfilled and happy in life, a person cannot be attached to any one thing because this thing can cause suffering.

What does Buddha say about true love?

In true love, theres no more separation or discrimination. His happiness is your happiness. Your suffering is his suffering. You can no longer say, “Thats your problem.”
