My fiancé never does anything with me anymore

Y’all my fiancé literally NEVER wants to do anything with me. Literally all we do together is go eat. He doesn’t want to hangout with friends anymore or literally do anything I want to do. He’ll make plans for us to go somewhere or something like run errands or go to town for something but as soon as I try to he doesn’t want to go. I do everything he wants to do whether I want to or not. He’s always saying he needs to “relax” but as soon as something comes along that he wants to do he all of a sudden is done “relaxing” and ready to go.
