Here are some quotes about people using you that I found:
- "The opposite of love is not hate; it is use. Use is the abuse of love; in fact, it betrays love. When we use people, we are betraying the trust they have placed in us." - Bell Hooks
- "People try to constantly use me and I hate it." - Tracy Emin
- "Men are used as they use others." - Bidpai
- "Don’t take advantage of each other, but fear God!" - Leviticus 25:17
- "Stop crossing oceans for people that wouldn't even jump puddles for you."
I hope this helps!
