You can be bit in the leg by a rattlesnake and seek help to heal your wound, or you can run after it and let the poison take your leg. The same is true with love.
I have always found it odd that people who think passive aggressively ignoring a person is making a point to them. The only point it makes to anyone is your inability to articulate your point of view because deep down you know you can’t win. It’s better to assert yourself and tell the person you are moving on without them and why, rather than leave a lasting impression of cowardness on your part in a person’s mind by avoiding them.
