Confused of love

Why is it the one you love never tends to feel the same way as you do? And why is it when you find out things have come to an end, you can't let go, because you know how much that person means to you, and how special he/she is. Why is it the minute others find out you are single they believe they have all the answers for you such as trying to push you forward into yet another relationship? Or all the jerks, or maybe a few nice men even will flock to your side trying to win you over.

All I wish I could do is turn back the clock and have another chance at trying to set things right, figure out where things started to go wrong and fix it, to be able to express myself as I wish I had how long ago to the one that means the most to me. I don't want to leave certain people in the past and move forward.

I know I may be sounding stubborn and selfish, but its just how I feel and sometimes certain things are harder to let go of than others.
