have you eaten? (i love you). did you get enough sleep last night? (i love you). how do you feel today? (i love you). did you have a nice day? (i love you). will you come on a walk with me? (i love you).
Please, if you are no longer interested in someone, let them know. Slowly distancing yourself, ignoring calls, and giving half-hearted responses hurts them more than simply being honest.
