I've had a few instances with exes who struggle to let go and move on. Online I've had unwanted attention from guys who are probably just being opportunistic. At first I enjoyed the attention but then its endless requests for photos and declarations of love and never being able to take no for an answer. I've had to change email addresses and forums accounts because it was becoming such a nuisance. It's hard to believe how fixated and obsessed some people can be. You worry about what they might do to you or themselves. Now if I even get a hint of crazy I run a mile!
