Is loving God something that you do on your own, or do you do it with others?

Loving God is both something we do on our own and with others also. We first start out with a desire to love God and that grows within us.
As the desire grows, God allows the cares and issues of life to compete with our desire for Him, and this gives us the opportunity to choose Him over our own desires.
In time, as you go along, these external cares and issues of life will be people. In loving these people and staying true to the Lord, you will find pace with God. Yet some of these you will love will be your enemy.
To love your enemy, truly love them, you will need to encounter more of the love of God. So the external can either drive deeper the quest for the love of God or it can destroy it all together. While good people can help you too, it is actually the “not so good” that will end up blessing your life as they are the refiners fire to you.
