I found the closure that I needed, short of having what I thought was a breakdown, it was just the release of emotions that I needed. Although most people would say, 'She's just a dog', my emotional issue came with the information from the ex that he would need me to pick him up when he has to put her down. I didn't want to be his crutch anymore, so i didn't respond in a manner to proud of, so the guilt just got to me.
Then I heard 'I Believe' by Diamond Rio.
She knows I love her and always will, I found the strength I needed to say goodbye to both of them, so for me the song has 2 separate meanings, but the same outcome. Whether I am present or not, life moves forward, and I truly have.
