If wisdom and age has taught me anything it’s that if husband, wife, kids, friends or neighbors don’t want you in their life....say Goodbye and just Move on. Don’t put your eggs in someones basket. You can’t make people like you or want to be around you. You only reduce your life when you depend on that.
Your observation is true and accurate, but some people just cannot deal with rejection. Can. Not.
Obsession is a dangerous and tedious thing.
