Kevin, it definitely shows that you have grown that you know
that what you did at the time was a mistake. And I think it was really great of you to come on here and "fess up" about it as an example.
But I think many of us do the "ignore it and it will go away" in life, not only in relationships but everything. I know it is very hard for me to face any kind of confrontation. (Yeah, I know I do it here all the time, LOL) But here on the forums I'm not looking someone in the face. If I have to confront someone either face-to-face or on the phone, I will quite often have a panic attack. It is one reason why my Mom is still capable of reducing me to tears of frustration!
It is hard to hurt someone. That's good, it means we are good and caring people.
But I think of breaking up with someone by facing them as opposed to ignoring them as tending a wound.
The breaking up is going to hurt either way; but if you are hionest and forthright it is like pouring alcohol on the cut - it hurts really bad at first, but it heals cleanly. If a person is just left wondering, then the cut is just left open to fester and become infected - it never really heals.
