Depends on the circumstances-it is helpful to tell the other person you feel ignored & then to give them a chance to respond to you before you remove yourself completely from the relationship.
Discussion
What if you tell the other person how it makes you feel and they answer that they want to be free to ignore others and not respond? That a connection that does not allows this freedom of ignoring, is a connection they don't want to nurture?
It seems to me that if that person was really interested in you they would have responded differently, in a kinder, more compassionate way. I would kick him/her to the curb and don’t look back.💯
