For what it's worth, I don't think that Frank was trying to re-ignite an old flame. I hope not anyway. Although I appreciate and agree that even calling an old flame could lead to that.
The past is the past. It can't come back like it was back then. It only exists in our memories now.
More importantly, confusing your mind and emotions with happy past moments that did not involve this person who is currently making your life hell does nothing to help today. Often makes it worse.
Good warning Frank. Just in case.
Blessings,
Bill
