Getting over someone
I've had the beginnings of regret and obsession over "what went wrong" and so on, but if you're honest with yourself, you know. We all know. The trick to getting over it is to start dating, not wither on the vine for years. Honestly, if it's over, it's over. Start anew with someone else. I'm an old fart, I can tell you from experience, don't backtrack. It didn't work the first time, it'll fold a second time if you backtrack and start over.
