I let a couple get away, but I just see it as it was not meant to be, you're only 27, you have sooo much time, forget about the past, don't focus on the future, focus on now, be the best you can be, right now, in every way, health wise, eat right, work out, treat everybody with respect, unless they give you a reason no to, separate yourself from negative people, and when you are in a situation where you meet somebody - go for it, have no fear.
