I'm married (happily), but recently a photo of my first boyfriend flashed up on my Facebook newsfeed. I hadn't given him a thought since we broke up at Uni, but I was intrigued to see how he looked now and photos of his family, and then I started remembering all the nice and funny times we had together, and how special it was being "first loves". It's really hard to get him out of my head now and weird as we work near to each other so I keep thinking/hoping that we'd bump into each other. I'd really like to get in touch with him but not for anything more sinister than to say hi and just have a chat. There is no way that I'd contact him as that would open a can of worms, but I'm finding it hard to get him out of my head now!! What should I do?
