Hi Dave,
I don't usually ring in on your threads to give my advise....but, I wanted to tell you what I think about this situation.
You can't be scared of life or freeze in the spot you are in now. Take a chance....take MANY chances. That is the only way to start getting back to being YOU. Maybe you will have a great time, maybe you won't......but, it won't hurt. Don't overanalize things....and get out of the past. Make NEW memories in Myrtle beach! That doesn't mean you are putting less value on what you and Amanda went through......
It seems you are gun-shy about life now, and that is not how you want yourself to be, so CHANGE. Trust me, we all have pasts that can haunt us if we let them....Just try not to let them. ((((((((HUGS)))))))))))))) Go have some fun!
