We are meant to love Radha Krishna and be attached to them and live physically in the world.
In the world, we have to be sensible, right? You can't leave your family duties. You can't leave your work. You have to be sensible and you have to be realize that the world is not always a good place and there are people who may try to trick you and take advantage of you. You have to be aware of your situations in the world. So, you keep living properly in the world but you start diverting your desires towards Shri Krishna.
So, you are not giving up anything. You are just diverting the desire towards Shri Krishna. Then, your mind will start to get the real happiness and it will recognize, “Oh! I had never got fulfillment from all these things. Now, I am getting real fulfillment. This is what I was looking for all along.”
This is the beginning of our devotional journey and as we keep practicing devotion, the mind gets more and more attached on the Divine side until finally the heart is fully purified and we receive Shri Krishna's ultimate Divine grace and we actually experience that ultimate Divine happiness.
So, the main point is on the path of bhakti, it is not the path of ending desires or attachments. It's the path of diverting them to the correct direction so you get the correct result what you were desiring all along anyway which is aanand (pleasure).
