some of u set standards for yourself that wouldnt be normal in any irl relationship
of course your partner loves you even if you dont dedicate art and shrines and gifts to them!!! of course you don't need to dedicate every single second of your time to them! they still love you!
relationships dont Need to be constant gushing and one-upping your last efforts to declare your love to your partner. they love you as an individual. and if they know you love them, that's enough.
