This is so true! I’ve made exactly this mistake for years until I realized how wrong I was! Nowadays, I often have to tell my boyfriend that he is not responsible for my happiness at all.
Sometimes, when I am feeling down and sad, my boy tells me how he feels responsible for my sadness, that’s when I explain he is not in charge of my happiness at all. His only job is being kind, being by my side and being honest with me, but definitely not making me happy. Learning this was a true gamechanger for my relationship!
