If there is an issue with you and another person who is important to you and it appears that it will never get better, move on.
If it appears that they will never know what they mean to you or that they just don’t care or want to bother with it, dump it and get busy putting your energy into something more constructive and beneficial for all.
Don’t waste away in denial like I have been doing for 40 years.
There is something better you could be putting your energy into.
If do not dump it and move on, you are carrying a sign that says, “Sure, you can damage me and I won’t stop you.”
It isn’t easy to let go, certainly if you care about that person, but nurturing them in order to allow them to damage you just isn’t what healthy relationships are made of.
