(Nick Galifianakis for The Post) | Adapted from an online discussion. Hi, Carolyn: Many years ago, someone in my life caused me a lot of heartache. Then they moved away and I moved on fairly quickly. Now they've come crawling back. It's only been a short time since they returned, but so far they are remorseful and it does seem they've changed for the better. However, their return has opened old wounds. I haven't thought about these things for years and have even forgotten many details; now I'm having a hard time getting past them despite having been over them for a long time. Things won't work out with this person if I can't let go of the past. So my question is, how much does the past matter as long as this person is treating me well now? — Heartache |
